What is a decibel?
The other thing that is interesting is how humans perceive low tones. A 300 hz tone at 134 db will be perceived as lower in volume than a 2000 hz tone at teh same db level. "A weighting" is typically used to account for this phenomenom. |
yup. but nowhere did i say the "sound power level". i stated twice as loud would require a 10 dB increase.
looking at the different natilus horns stebel offers, i would say they use the same diaphragm and very similar horns, however the 300 hz horn isn't as loud as the higher freq horns because it is at a lower freq. i'd be interested to see what a 600 hz horn does with the 300 hz horn.
