To add to the continuing attempt to suggest sighted bias doesn't exist or
is a natural product of the human perception process, consider: http://www.sciencedaily.com/releases...0220074652.htm In short, while different areas of the brain are used to interpret input from the various senses, there is overlap in the areas such that sight can influence sound perception. Seeing a yamaha and pass labs amp side by side and doing sighted "tests" will trigger this overlap, make it imposibble to know which amp is being used and the "tests" do as well as random choices; just as the now famious test demonstrated. |

One person here says it is as simple as placing a cloth over connections
of the item under test, all other visual clues remaining. Just turn out the lights, or more conventionally, a dbx setup where all visual clues are present at all times and the test is in full control of the testee. Removing knowledge of visual clues is simple, not knowing which item is under test is the thing that makes the results the same as random choice would produce. What the artcle shows is the perception of "real difference" can be explained by the adjacent perception process of hearing and seeing in the physical brain. The tests which remove knowing which visual clue goes with which hearing event makes this process random, or more likely it doesn't happen at all because visual clues remain the same while hearing clues change without the testee's knowledge. This can be reversed too, in the instance where hearing and seeing clues remain the same but the testee is told a switch is made, we know that produces results based on another kind of bias of expectation which is entirely the product of the perception process cut off from the actual clues as intake. I don't believe anyone here denies that sighted bias exists.

I don't take your point, the two terms in this context seems a case of a
difference without a distinction. Any scientific "explanation" is at the same time a "suggestion" of an application of an observed principle. Brain activity in the seeing area spills over into the hearing area, exciting perceptions that are not inherent in the physical sound waves as they arive at the ear. Remove the adjacent excitation and the perception receeds in the hearing area, that is the thesis as the research suggests/explains. That is why the subjectivist can claim with such vigor that something is really happening, it is, but only as a perception product and not a realistic experience of the physical event. The perception experience is so vivid as to motivate the adoption of any number of explanations/suggestions in an attempt to tie it back into the physical realm. The oft repeated "just trust yyour ears" is in fact perhaps not an appeal to the function of the ear but the spill over in adjacent areas that are down stream of ears. The article as given (not the original publication, btw) only suggests a possible physical basis for your proposition. It does not explain it. Kal |

I can hear differences between cables. I can hear differences between amps. Curiously, I can hear these differences better when I turn out the lights and allow my hearing full access. Perhaps those who claim 'sighted' tests are invalid are picking the wrong reason, if they claim that 'knowing' which amp is being tested causes bias. The simple fact is that listening in a lighted room causes your brain to expend energy on vision and have less 'processing power' left for hearing. When I conduct comparative tests, I always use extended in-the-dark listening. |

By the same token, seeing the components allows one to 'appreciate' a system's performance in a way that hearing them alone, does not. But that 'appreciation' has nothing necessarily to with determining audible difference. It's just another way to enjoy your experience. Keep the lights on at concerts please.

It's just another way to enjoy your experience. I agree with this. I enjoy good looking equipment and I enjoy a aesthetically pleasing listening envirement. It does make for a better experience over all. Ever notice that orchestra auditions these days involve a blind judging component? I have never been to such an audition. |

Someone said they use extended listening in the dark to avoid light
stimulation and do hear differences. The key is not the level of illumination but the knowledge of which is in the system. It is suggested that visual knowledge of which gear is active provides the overlap in the hearing and seeing parts of the brain, in addition to the anticipation bias of which is thought to provide some difference beforehand. Dark listening only eliminates one of the perception altering sources. The thing to do would be dark listening without knowing which bit of gear is active, which would remove the anticipation bias also. One way to remove the visual input would be to have both bits of gear contained in boxes of identical appearence, or just put a cloth over the connections obscuring which is active; as has been suggested. If removing this knowledge produces results tending to random, as it apparently does, then we know knowledge of what is active is a perception distorting input. If someone wants to test level of illumination as a varible, it can be tested, but I fear it a waste of time. This has been done already in another form. It has been shown that blind folk do no better in hearing differences then do sighted people when knowledge of what gear is active is absent. |

The key is not the level of illumination but the knowledge of which is in the system. Prove it! There is NO evidence to prove that the senses are influenced by 'knowledge'. I wonder what the authors of this reference book would make of that claim: http://www.amazon.com/gp/reader/0849...23#reader-link You can view the Table of Contents at Amazon. Notice particularly the section headings of Chapter 4, "Factors Influencing Sensory Verdicts'. For somre reason, Mssrs. Meilgaard et al., who are on their third edition of this book, PERSIST in including discussion of such fictions as 'expectation bias' and 'mutual suggestion'. And why do you suppose the esteemed authors of *this* well-regarded tome on psychoacoustics, Drs. Zwicker and Fastl, discuss 'bias' in the in the 'Methods and Procedures' section, so early on in the book? http://www.amazon.com/exec/obidos/tg...glance&s=books And why, pray tell, does this dictionary of psychological testing contain an entry for the term 'blind study'? http://www.amazon.com/exec/obidos/tg...glance&s=books Please, someone write to these authors and let them know it's all a mistake. Michael Scarpitti says so. -- -S. "They've got God on their side. All we've got is science and reason." -- Dawn Hulsey, Talent Director |

Prove it! There is NO evidence to prove that the senses are influenced by 'knowledge'. This is arrant nonsense. There is a *vast* slew of such evidence, starting with the classic 'false sighted' test where nothing is actually changed, but enthusiastic audiophiles duly report 'night and day' differences when they *think* that a tube amp or magical cable has been introduced. I too have observed sighted bias in a group of people as well as read reports describing the effects. In addition, it is the rare individual that does not succumb to peer pressure, arrogance, and other social factors which would then influnce the conclusion or reporting of his findings. r -- Nothing beats the bandwidth of a station wagon filled with DLT tapes. |

If you know which piece of equipment you are listening to at any given moment, your knowledge and beliefs about that item are going to influence your perception no matter how many times you tell yourself otherwise. That said, there is absolutely nothing wrong with allowing your beliefs to enhance your enjoyment of music when using a particular item.

You may hear the inflections and other important aspects of a vocal performance but it is affected by the poor recording. It changes the affect of the performance. It changes the affect of the music as a whole. That is why the art of the music and the sound of the playback are inseperable. This is only true for the tiny minority of music lovers in the world who are audiophiles. The vast majority of music lovers do not find mediocre sound reproduction to bother them in any way, or to detract from their appreciation and enjoyment of music. For them, art and sound ARE quite separable, and they care far more about the former.

It cannot make a Harmon-Kardon amp sound consistently(!) different from a Hafler amp, especially when I have no idea how each is supposed to sound. It cannot make five different amps sound different from each other, and consistently so. The same thing applies to auditioning audio equipment, whether amps, speakers, cables or whatever. If you know which piece of equipment you are listening to at any given moment, your knowledge and beliefs about that item are going to influence your perception no matter how many times you tell yourself otherwise. I have said this before, and I am going to say it again, for the LAST time: I had NO beliefs about how these amps were supposed to sound. It was a 'blind' trial, in the sense that I had not listened to any of the amps before bringing them home for listening tests. Hafler PS Audio Harmon-Kardon Bryston Sony They all sounded different. How can my 'beliefs' affect my judgement, when I had no 'beliefs' to start with?! I listened with Stax electrostatic earspeakers connected directly to the power amps. Perhaps your system is not as critical. But DON'T tell me I cannot hear differences between amps this way. Hellen Keller could hear them! |

You must also understand the drugs are tested on people who are ill and are not necessarily the best judges of the effects. ----------------------------------------------------------------- Here is a typical study, on Zoloft: ----------------------------------------------------------------- Table II Treatment-Emergent Adverse Experience Incidence in Placebo-Controlled Clinical Trials* ----------------------------------------------------------------- Percent of Patients Reporting Zoloft Placebo Difference Adverse Experience (N=861) (N=853) Percentage Autonomic Nervous System Disorders Mouth Dry 16.3 9.3 7.0 Sweating Increased 8.4 2.9 5.5 Cardiovascular Palpitations 3.5 1.6 1.9 Chest Pain 1.0 1.6 -0.6 Central and Peripheral Nervous System Disorders Headache 20.3 19.0 1.3 Dizziness 11.7 6.7 5.0 Tremor 10.7 2.7 8.0 Paresthesia 2.0 1.8 0.2 Hypoesthesia 1.7 0.6 1.1 Twitching 1.4 0.1 1.3 Hypertonia 1.3 0.4 0.9 Disorders of Skin and Appendages Rash 2.1 1.5 0.6 Gastrointestinal Disorders Nausea 26.1 11.8 14.3 Diarrhea/Loose Stools 17.7 9.3 8.4 Constipation 8.4 6.3 2.1 Dyspepsia 6.0 2.8 3.2 Vomiting 3.8 1.8 2.0 Flatulence 3.3 2.5 0.8 Anorexia 2.8 1.6 1.2 Abdominal Pain 2.4 2.2 0.2 Appetite Increased 1.3 0.9 0.4 General Fatigue 10.6 8.1 2.5 Hot Flushes 2.2 0.5 1.7 Fever 1.6 0.6 1.0 Back Pain 1.5 0.9 0.6 Metabolic and Nutritional Disorders Thirst 1.4 0.9 0.5 Musculo-Skeletal System Disorders Myalgia 1.7 1.5 0.2 Psychiatric Disorders Insomnia 16.4 8.8 7.6 Sexual Dysfunction- Male (1) 15.5 2.2 13.3 Somnolence 13.4 5.9 7.5 Agitation 5.6 4.0 1.6 Nervousness 3.4 1.9 1.5 Anxiety 2.6 1.3 1.3 Yawning 1.9 0.2 1.7 Sexual Dysfunction- Female (2) 1.7 0.2 1.5 Concentration Impaired 1.3 0.5 0.8 Reproduction Menstrual Disorder (2) 1.0 0.5 0.5 Respiratory System Disorders Rhinitis 2.0 1.5 0.5 Pharyngitis 1.2 0.9 0.3 Special Senses Vision Abnormal 4.2 2.1 2.1 Tinnitus 1.4 1.1 0.3 Taste Perversion 1.2 0.7 0.5 Urinary System Disorders Micturition Frequency 2.0 1.2 0.8 Micturition Disorder 1.4 0.5 0.9 ----------------------------------------------------------------- *Events reported by at least 1% of patients treated with Zoloft are included. (1)% based on male patients only: 271 Zoloft and 271 placebo patients. Male sexual dysfunction can be broken down into the categories of decreased libido, impotence and ejaculatory delay. In this data set, the percentages of males in the Zoloft group with these complaints are 4.8%, 4.8% and 8.9%, respectively. It should be noted that since some Zoloft patients reported more than one category of male sexual dysfunction, the incidence of each category of male sexual dysfunction combined is larger than the incidence for the general category of male sexual dysfunction, in which each patient is counted only once. (2)% based on female patient only: 590 Zoloft and 582 placebo patients. ----------------------------------------------------------------- Other events observed during the premarketing evaluation of sertraline: During its premarketing assessment, multiple doses of sertraline were administered to 2710 subjects. The conditions and duration of exposure to sertraline varied greatly, and included (in overlapping categories) clinical pharmacology studies, open and double-blind studies, uncontrolled and controlled studies, inpatient and outpatient studies, fixed-dose and titration studies, and studies for indications other than depression. Untoward events associated with this exposure were recorded by clinical investigators using terminology of their own choosing. Consequently, it is not possible to provide a meaningful estimate of the proportion of individuals experiencing adverse events without first grouping similar types of untoward events into a smaller number of standardized event categories. ----------------------------------------------------------------- The same thing applies to auditioning audio equipment, whether amps, speakers, cables or whatever. Unwarranted claim. No basis from generalization from drugs to audio. They are completely different sorts of experiences. If you know which piece of equipment you are listening to at any given moment, your knowledge and beliefs about that item are going to influence your perception no matter how many times you tell yourself otherwise. What knowledge? What belief? What did I know about Harmon Kradon, PS Audio, or Denon BEFORE I tried them? Nothing! I did not listen to these products before I tried them out. That said, there is absolutely nothing wrong with allowing your beliefs to enhance your enjoyment of music when using a particular item. Just don't confuse that enjoyment with the results of a double-blind test under carefully controlled conditions. They are two different animals. I have no 'beliefs'. |

I don't have to, since all existing evidence and all medical and engineering knowledge, says that I am right about this. If *you* wish to claim otherwise, then that is an extraordinary claim, and the burden of proof is on *you*. Or might this be, just might it be, and assertion, a judgement, your considered opinon? It's a considered opinion based on a *total* lack of evidence to support the existence of 'cable sound'. Naw, it surely is a "fact". It surely is a good working premise - unless you can offer *any* shred of evidence in rebuttal.

Last I looked, this thread was about amplifiers and what Michael feels he heard in comparing five of them. Clearly, you didn't look at the thread title. Michael is claiming that he can't possibly be mistaken in what he thinks he hears in sighted tests, we are pointing out that it's not only possible, it's highly likely.

Merely brevity - the disclaimers still apply to amps, but may safely be extended to *all* so-called 'audiophile' cable. -- Stewart Pinkerton | Music is Art - Audio is Engineering |

The point of course is that no human can do this, in the same way that there is *no* evidence that *any* human can tell apart two nominally competent cables (i.e. not comparing 8AWG to 28AWG or other such silliness). oops..a qualification slips out. Whup!...here comes the flow of "absolutes"..things like "no human" and the like...NO evidence. Gads...in who's book?..what mindset?.. ..this redundant flow of absolutes. Sorry, these newsgroups are full of this. A bit overworked...perhaps trite? Not convincing! Perhaps, we have a group that missed their calling... ..neuro-research..or some study of the myriad of variables in the mental processes on the analysis of input from external sources. Indeed so - and there has been a raft of research over the last century into human hearing thresholds and acuity, all of which supports the notion that 'wire is wire'. Granted there might well be research on hearing "thresholds" and "acuity"...but, this issue is not about thresholds and acuity....those studies had to do with detecting a frequency range upwards of 10 to 15k cycles...mainly in factories..I have discussed that issue with those that administered those test and one would not believe the variables in frequency range that first detection occurs...there is a lot of difference in the populace out there and their ability to hear even up to 10K cycles. (Hertz in the current vernacular). Just one of the variables I keep bringing up. Oh well...these facts are wasted here! So, I respect your hearing differences...no arrogance here about what you do or do not hear. If one hears cable or amplifier differences..so be it! However, not one has been found who can do this when they don't *know* what is connected, so your 'respect' is rather misplaced. Gads...we've missed the point, as always....it is not "knowing what is connected"..it is about one cable sounding a bit better or worse than another. Simple issue, but hard to grasp? Leonard... |

what is connected, so your 'respect' is rather misplaced. Gads...we've missed the point, as always....it is not "knowing what is connected"..it is about one cable sounding a bit better or worse than another. Simple issue, but hard to grasp?" It is about knowing, more important how we know what we know; gads. If one tests you and you hear a difference in wire and then by putting a cloth over the wire connections you are no longer able to do better then random, we now know something; gads. What we know we now know is that the perception of difference is directly related to knowledge of which wire is connected; gads. We then are justified to deduce that the "better/worse" is produced in the brain and not in the properties of the wire; gads. If we in fact know something else in that instance, please do tell us that we may grasp; gads. |
