) Noise from the street is an occasional problem which was helped a little by drapes on the window. An additional drape across the doorway made only a slight improvement in isolation and was really in the way, so we gave it up.
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.
The best approach to adding soundproofing is to try simple techniques first and to move to the high caliber options only when needed.
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.

A mono signal fed to both speakers appears to be centered precisely between them, and any imbalance in a stereo signal is immediately obvious. The room has a soft, comfortable ambience and the music produced there sounds just fine out in the real world.

brick – a staple of Brazilian architecture – takes centre stage in the Campana’s design, forming not only here the fixtures and furniture but the flooring, ceiling and an entire wall that stretches from the exterior courtyard right through into the interior.
This procedure is intended to be used for estimating noise suppression of existing designs or for designing new acoustic treatment panels and duct configurations to achieve desired suppression levels.
