• Intensity. The correlation between sound intensity and loudness. The decibel (dB) is the unit used to measure sound intensity. The range of normal hearing sensitivity of the human ear is between -10 to +25 dB. Sounds below -10dB are generally imperceptible. A pilot who cannot hear a sound unless its intensity is higher than 25 dB (at any

  • The range of human hearing is generally considered to be 20 Hz to 20 kHz, but it is far more sensitive to sounds between 1 kHz and 4 kHz. For example, listeners can detect sounds as low as 0 dB SPL at 3 kHz, but require 40 dB SPL at 100 hertz (an amplitude increase of 100).

  • Boosting around 1000 Hz can give instruments a horn-like quality. Excess output at this range can sound tinny and may cause ear fatigue. If boosting in this area, be very cautious, especially on vocals. The ear is particularly sensitive to how the human voice sounds and its frequency coverage. Sine wave example at 1000 Hz

    Powerful but deep sounds seem soft while much less powerful sounds in higher frequencies seem very loud. A woman speaking in English uses frequencies from 200 Hz (the sound of J or M) to 5,000 Hz (the sound of S or th). A very deep male voice might go as low as 100 Hz.

    For the best results we HIGHLY recommend using a good set of headphones or better than built-in computer speakers. Muffler sound is all about BASS. Cell phones and built-in computer speakers will not give you the true experience of the Muffler sound. The current peak power, in decibels, for the sound being recorded. A return value of 0 dB indicates full scale, or maximum power; a return value of -160 dB indicates minimum power (that is, near silence). If the signal provided to the audio recorder exceeds ±full scale, then the return value may exceed 0 (that is, it may enter the positive range). When measuring sound, we use the following logarithmic formula to determine the sound pressure level (SPL) in decibels. Here p is the sound pressure we are measuring, and Pref is our reference, the pressure of the smallest sound we can hear, 2.0×10-5 Pa (you remembered this, right?). For example, if we measure a sound pressure of 0.4 Pa, we ...
