Why magic at 80 db?


I have Salk SoundScape speakers that have an Accuton midrange driver. When I listen to music at moderate levels, the music sounds plain. There is little that would make me think that I was listening to a great speaker. When I turn the music up till it reads 80 to 85 db on my Rat Shack meter, magic happens. I guess it is like that with live music, but I am not sure. I never take my meter with me. I am just confused. Anybody have any comments?

If I remember right, when background noise at work is 84 dB or 104 dB and above, during a 8-hour time weighted average, OSHA requires single and double hearing protection, respectively. Sound pressure doubles with each 6 dB of volume gain.

If your hearing is good enough to enjoy all the music near 80 dB, that's great. The sensitivity of our hearing naturally rises much quickly near 80-86 dB and up. Too much sound pressure causes our ears themselves to add distortion, with or without pain, our warning system to back off.

Smoother, well-balanced systems can obviously be played and enjoyed at higher sound pressure levels. Moderate music volumes sound good, yet, there's a premium sound pressure window that's a combination of the music system and our uniquely different ears. As the sound pressure approaches 80 dB, the doubling of sound pressure with each 6 dB gain pressurizes our ears when they're naturally much more sensitive to volume gains.
