A general model of processing stimuli suggests that when information does not provide informational value, then we gradually begin to ignore it. Such a model is consistent with the experience of many people in relation to background traffic noise when moving from a quiet to a noisy neighbourhood. I.e., the frequency with which external traffic noise enters ...

The frequency is individual, and known as tinnitus frequency or pitch. From Okamoto et al., 2010: Our target notched music introduced a functional deafferentation of auditory neurons corresponding to the eliminated frequency band, and because this frequency band overlapped the individual tinnitus frequency, the notched music no longer ...

Jens' answer is pretty much spot on, but misses the fact, remembered from my undergraduate lectures, that your ears actually partially 'turn off' when you speak (or chew), in what's called the stapedius reflex (wikipedia). The most common reference I've seen for this is Møller (2000), which unfortunately is a book, but I'm sure more information could be ...

I think this is not a psychological syndrome but just a reflection of the physical procesces. As such it might not be on-topic for this site. Having this said, here is a quick answer. When you hear your own while speaking, the sound source is in a different place than it is, when you hear a recording of your voice through a loudspeaker. In addition, when ...

It greatly depends on what you mean as 'noticeable' - what/why do you want to synchronise, and how it reaches the ears from physical speakers. Keep in mind that a sound source being 30cm/1 feet further from the ear is about the same effect as a millisecond of delay (speed of sound ~340m/s) - thus, synchronising on the order of microseconds is generally ...

The answer ought to be a qualified "Yes." We don't only hear what we want, in as much as motivation has zero direct control over the transduction of auditory signals in a sensory sense. Motivation affects which way we turn our ears and whether we keep them in a room with sounds we want to hear vs. a room with sounds we don't want to hear, but if those sounds ...

Here's a study on Brain Response to One's Own Name in Vegetative State, Minimally Conscious State, and Locked-in Syndrome: http://archneur.jamanetwork.com/article.aspx?articleid=791093 Background A major challenge in the management of severely brain-injured patients with altered states of consciousness is to estimate their residual perception of the ...

Following the comments you've received, I'll add my own subjective answer in the affirmative to your first question. I think we've already compiled enough votes and comments here that support @JoshGitlin's unscientific answer to say that there is some empirical basis for theorizing the existence of a "taste" acquisition process in music. Nonetheless, here's ...

There are two sound pathways by which we hear: bone conduction and air conduction. The air conduction pathway involves vibrations in the air being transmitted from the ear drum, through the bones of the middle ear, which act as a lever, to our fluid filled inner ear. The lever acts as an impedance matcher between the air and fluid filled inner ear. It ...

First, a definition: "Synaesthesia is a curious condition in which an otherwise normal person experiences sensations in one modality when a second modality is stimulated." [1] There are two basic explanations for this phenomenon: the hyperconnectivity hypothesis and the disinhibition-unmasking hypothesis [2]. The former says that the condition results from ...

I am not aware of any use in using "high audio frequencies" in commercials, but there is a history of making commercials louder (presumably to attract attention). There are laws prohibiting increasing the loudness of commercials (e.g., CALM Act). Increasing the loudness, without remotely adjusting the volume on the TV is not a trivial thing and potentially ...

Auditory information is conveyed to the brain from the cochlea via the VII cranial nerve (aka auditory vestibular nerve). Under standard conditions the vestibular system gets activated when we move our heads. If we spin around rapidly this can obviously make us feel dizzy and nauseous. The vestibular system can also be activated do to other causes. For ...
