When computing the STFT (with the code below) of this audio file, I noticed that max(abs(STFT)) is around 248.33. (more generally, it seems to be approximately fftsize/4 for this particular file). Even after doing magdB = 20 * math.log10(abs(STFT)) to have decibel values, we get a max of 47.9 dB .

デシベル (英語: decibel 記号: dB)は、ある物理量を基準となる量との比の常用対数によって表したものである。. 音の強さを表す単位、または音圧レベルの単位。

its adaption to how the human ear responses to sound - the human hearing, and; the possibility to measure noise with "low cost" instruments; Maximum acceptable Equivalent Sound Level - L eq-at some locations: The decibel level of a sound having the threshold intensity of 10 −12 W/m 2 is β = 0 dB, because log 10 1 = 0. That is, the threshold of hearing is 0 decibels. Table 1 gives levels in decibels and intensities in watts per meter squared for some familiar sounds. Microphone maximum SPL. Bit-depth.

Maximum SPL. First, not every microphone can capture loud sounds at all. Some may top out at certain decibel ratings and are unable to capture louder sounds. This measurement is known as maximum sound pressure level . The main advantage with dB(A) - the A weighted noise or sound measurement - is. its adaption to how the human ear responses to sound - the human hearing, and; the possibility to measure noise with "low cost" instruments; Maximum acceptable Equivalent Sound Level - L eq-at some locations: Maximum output of speaker (dB) based on SPL and Max power: Enter your Speaker Sensitivity (SPL): (dB 1W/1M) 1 watt/1meter SPL (sound pressure level) - Usually printed on the back of your speaker cabinet.
