Introduction to Acoustics - Reverberation Briefly Explanied

2010-01-29T00:12:00.001-08:00

Rev-erb-er-a-tion -

Also known as Reverb, Echo, Though echo also refers to Pre-delay which is time between Direct sound sources and the first reflection or "the firse echo".

Shortly after a direct sound, the number of reflections increases to the point were individual reflections become indistinguishable and we are in the last time period: (the reverberation time).

At this point reflections are coming from all directions now and are so frequent that they form together to form a diffuse, gradually decaying reverberation which envelopes the original sound with its warmth and body.

Because sound radiates in all directions, the intensity of the direct sound is relatively small in comparison to the intensity of reverberation.

Bass Trapping Methods - Absorbers,, Resonators &, Corner Traps

2010-01-05T01:16:00.000-08:00

Bass Trapping Methods - Absorbers, Resonators & Corner Traps

- 1/4 Wavelength Method

This method makes use of the fact that the best place to trap a sound wave is 1/4 of the way along it's length. This point is known as it's anti0node. the 1/4 distance of a particular wavelength will depend on the sound waves frequency. Low frequency waves will ofcourse have longer wavelengths and thus more distance is needed in order to trap the wave at 1/4 of its length.

- Flexural absorber (a.k.a. panel absorber).

This bass trap consists of a box attached to a wall with a dampded air space in it. the front panel of the box needs to be compliant (flexible). The frequency range that the box is capable of absorbing will depend on the box depth. Mineral wool (rockwool) is placed inside the box filling it approximately half full thus allowing damped air inside.

- Tube Trap absorber

A tube trap consists of a hollow tube such as a PVC pipe lightly packed with absorbent materials . These traps are usually placed in corners of rooms were excess low frequency build up is present. Like all the other bass trapping methods, the frequency range a tube absorber will trap will depend on the diameter and length of the trap.

- Helmholtz Resonator

This is a damped air space that is usually built into a wall that has a thin neck similar to a bottle shape. The front panel of the resonator will be perforated. The benefits of this bass trap is that it can be very specifically tuned.
