Apart from matching phase and level to the top speakers, all adjustments I did on my sub was against my room, and that’s the difficult part - which you can’t really do much about with full range speakers, unless the woofers have their own amps and processing. Or I could get another 15"… Just need to glue and bolt everything in my room down first!Īnyway, indeed bass is complicated, and I agree that subs a better solution than large full range speakers, unless possibly if you have a big and very well designed room. And there is an 18" version of this driver. I don’t even have bass reflex on my current 15" sub! (Prototype just slapped a new driver into an old box to see where I am, before spending time on building something proper.) Even tuned and EQd to play linear down to 25 Hz (-3dB 20 Hz), it packs enough punch for my needs anyway. © 1996-2005 by All Rights Reserved.Some crazy guy built two massive exponential horns under the floor, with “vents” into the room… Totally something I might do, if I found myself with enough time and resources! Except, I’m not a huge fan of horns, due to the delay.

To convert to decibels, simply multiply the number of Bels by 10.

So a noise that is 30 db louder is 1000 times as loud. Here's a list of common activities with an estimated sound intensity level. The decibel scale defines the threshold of hearing at 0 decibels and the threshold of pain at 130 decibels. Since the range of hearing is so large, scientists invented a logarithmic scale which is based on multiples of 10. The loudest sound we can hear is about 1,000,000,000 times louder than the softest sound we can hear. Human hearing is extremely versatile, being able to hear very soft sounds from 10-12 W/m2 to very loud sounds at 1 W/m2 where the sound starts to become painful. You can still see pipes in old ships that the captain used to give commands to others in distant parts of the vessel. Note that if you make a sound in an enclosed area, especially one with hard walls that do not absorb energy, e.g., like a pipe, the intensity will not drop off with distance. If a sound is made in an open area, the intensity drops off quickly as you get farther from the source because the sound energy is spread in every direction. A microphone will measure the intensity of a sound and display the difference in the amplitude of the pressure plot. The more energetic the speaker, between speaking and yelling, the more energy is present in the resulting wave. Sound amplitude is a measure of the energy in a sound wave. It is measured in watts per square meter. In pressure terms, intensity is a measure of the amount of compression and rarefaction of the sound pressure wave.
