The threshold of hearing is generally reported as the Hz.
2.
The threshold of hearing at 1khz is 0 dB ( relative to . 0002 dynes / cm 2 ).
3.
The lowest equal-loudness contour represents the quietest audible tone the " absolute threshold of hearing ".
4.
The threshold of hearing is plotted relative to a standardised curve that represents'normal'hearing, in dB ( HL ).
5.
I'd also mention that Hungarian and English strike me as extremely similar when at the threshold of hearing, for example.
6.
By measuring this minimum intensity for testing tones of various frequencies, a frequency dependent absolute threshold of hearing ( ATH ) curve may be derived.
7.
The threshold of hearing is frequency-dependent and it has been shown that the ear's sensitivity is best at frequencies between 1 kHz and 5 kHz,
8.
Although the threshold of hearing is typically around 0 dB SPL, this is in fact very quiet indeed, and appliances are more likely to have noise levels of 30 to 40 dB SPL.
9.
Data acquisition in one-third-octave bands is required, followed by processing to yield a logarithmically-scaled value in decibels relative to a sound pressure of 20 micropascals, approximately the threshold of hearing.
10.
Among the results from this work is that the so-called third heart sound, " S3 ", formerly taught to be pathological, is actually produced by all hearts, but is merely below the threshold of hearing of most physicians.
