Deaf in one. Is stereo expereince possible?
On a non-music discussion board someone asserted that a person who is deaf
in one ear cannot expereince stereo or 5.1 or 7.1. In effect they can only here in mono with no differentation of spatial information. This doesn't seem right to me. What's the facts about impaired hearing and stereo and mutli-channel reproduction. |

What's the facts about impaired hearing and stereo and mutli-channel reproduction. Yes and no, the bits below from a site about Ambiophonics provides the answer. I urge all to read the entire site for a very different approach to multi speaker music reproduction and reproduction in general. http://www.ambiophonics.org/Ch_1_amb...s_2nd_edit.htm Regarding frequency shaping of the pinna,ie. the outer ear: "This side response is quite different from the dead ahead response and indicates that we are very sensitive to the direction from which sounds originate even if we listen with only one ear. For sounds directly rearward, the pinna cause a dropoff of 23 dB between 2500 Hz and 10 kHz. Other radically different frequency responses occur for sounds coming from above or below. The pinnae seem to be entirely responsible for our sense of center-front sound source height." snip "Although a one-eared music lover can tell the difference between a live performance and a stereo recording (and Ambiophonics works for such an individual) it is two-eared listeners that Ambiophonics can help the most. Two ears can enhance the listening experience in a concert hall (and life in general) only if there are differences between the sounds reaching each ear, at least most of the time. The only differences the sound at one ear compared to that of the other ear can have are differences in intensity, arrival time, and absolute polarity. In an acoustical concert hall or any real physical space, it is not possible for absolute polarity to be inverted at just one ear and certainly not at just one ear at all frequencies simultaneously. Thus we need only consider what the difference (or lack of difference) between the ears in sound arrival time and intensity does for listeners at a concert." |

We discern the position of sound sources by many means. Having two operational ears provides greater reliability and less ambiguity than having just one, and by quite a bit. But, there are many cases where accurate directional cues can be discerned using just one ear. For example, reflections by nearby objects in conjunction with foreknowledge about where those objects are, can be a source of directional cues. If you've got two operational ears, I strongly recommend taking whatever steps you must to keep things that way! ;-) |

You can experience stereophony partly by simply turning your head and hearing different sounds from different directions. Even for a person deaf in one ear, stereo is likely to be different from mono (depending on how the recording was made). But a person deaf in one ear would not be well equipped to critique a stereo system |

I have a teacher who is deaf in one ear from birth. She told me that she cannot tell where sounds are coming from at all. As a child, when her mother would call her, she would have to wander from room to room to look for her mother. Stereo is meaningless to her. That makes no sense at all. Anyone with hearing in one hear and with a sound coming from one side can simply turn 180 degrees and the sound will be perceived at a different amplitude. |

Subject's been covered already.
Surprising answer. http://www.hei.org/about/history/historyhouse.htm |
