WebSound pressure level (SPL) is a logarithmic (decibel) measure of the sound pressure relative to the reference value of 20 μPa threshold of hearing. The threshold of hearing is the quietest sound that most young healthy people can hear. Sound pressure level L p is measured in decibels (dB) and is calculated as follows:. L p = 20 log 10 (p/p 0),. Where p … WebdB HL (hearing level) is not the same as dB SPL (sound pressure level), which is an absolute measure of the pressure generated by sound wave. dB HL is determined by conducting hearing tests among a large test group to determine the "equal loudness curve" and the "minimum audibility curve." The data points on these curves are computed by …
WebThis was measured a number of years ago. Unless dB(A) is measured exactly to this, i fail to see how they should be identical. So 0 dB HL would be the minimum treashold of hearing for an average healthy male adult. -5 dB HL would be 5 dB SPL higher than average. 10 db HL would be 10 dB SPL lower and so on. I hope this helps :)
