If one ear has normal thresholds while the other has sensorineural hearing loss (SNHL), diplacusis may be present, as much as 15–20% (for example 200 Hz one ear => 240 Hz in the other). [citation needed] The pitch may be difficult to match because the SNHL ear hears the sound "fuzzy". Bilateral SNHL gives less diplacusis, but pitch ...
For the convenience of recording engineers, each player has to record their part on a separate track while listening to a click track – a metronome – and the clicks are then used to synchronize the tracks while the technicians adjust them to their taste and mix them. I know talented young musicians who can't do it; we can understand why.
Humans normally hear sound frequencies between approximately 20 Hz and 20,000 Hz (20 kHz), [18]: 382 The upper limit decreases with age. [18]: 249 Sometimes sound refers to only those vibrations with frequencies that are within the hearing range for humans [19] or sometimes it relates to a particular animal. Other species have different ranges ...
Sound spectrum: High frequencies are more quickly damped by the air than low frequencies. Therefore, a distant sound source sounds more muffled than a close one, because the high frequencies are attenuated. For sound with a known spectrum (e.g. speech) the distance can be estimated roughly with the help of the perceived sound.
The definition of sound, simplified, is a hearable noise. The tree will make a sound, even if nobody heard it, simply because it could have been heard. The answer to this question depends on the definition of sound. We can define sound as our perception of air vibrations. Therefore, sound does not exist if we do not hear it.
According to former professor at the University of Washington Bill Guy, "There's a misunderstanding by the public and even some scientists about this auditory effect," and "there couldn't possibly be a hazard from the sound, because the heat would get you first". [11]
Subvocalization, or silent speech, is the internal speech typically made when reading; it provides the sound of the word as it is read. [1] [2] This is a natural process when reading, and it helps the mind to access meanings to comprehend and remember what is read, potentially reducing cognitive load.
A cat can hear high-frequency sounds up to two octaves higher than a human. Not all sounds are normally audible to all animals. Each species has a range of normal hearing for both amplitude and frequency. Many animals use sound to communicate with each other, and hearing in these species is particularly important for survival and reproduction.
