No sound, just a tape of the mic levels at their usual setting with nothing going on. Now turn up the gain and play it back. If you can't hear any difference between the unrecorded and recorded portions of the tape you have reached your goal.
The amount of reverberation desired in a room depends on the activity going on. Musicians like fairly long reverberation times; between one and two seconds. This allows them to hear themselves play and enhances the harmonic effects of the music.
Silence is golden, or at least pretty expensive. Commercial recording studios cost hundreds of thousands of dollars to build because they must allow absolutely pelo sound to enter from a usually noisy urban environment.
A mathematical procedure is developed for calculating the parameters of a singlelayer perforated-plate acoustic liner in order to achieve a specified acoustic resistance and reactance for single-frequency excitation. The method includes the standard impedance terms, due to viscosity, radiation, and backing effects, and also the terms due to high sound amplitude and steady tangential airflow. Emphasis in the analysis is on these latter non-linear effects. Specification of acoustic resistance and reactance (at one frequency and set of environmental conditions) means that two quantities are used to determine the four liner parameters: fractional open area of plate (porosity of plate), thickness of plate, diameter of hole perforations, and depth of backing cells.

Some of this coloration is ok, even preferable, but eventually the room develops a tubby response. If we need a very dead room and bass buildup occurs there are devices called bass traps and Helmholtz resonators that absorb a restricted range of very low frequencies. The specifics for here designing these are beyond the scope of this article, but the general principle is the larger they are, the lower the frequency. The moral is that absorption should be used only in moderation, and only materials that soak up the full range of sound should be used.

Start with a rectangule of 3/8 in plywood as large as you can fit into the space. Cut a series of slots for the air to pass through, and cover the back with fiberglas, leaving the slots clear. Hang this at an click here angle in front of the duct and fit triangular pieces over the ends.
