In the design of public address and voice alarm system installations, acoustic and electroacoustic calculations are involved to determine power, lengths, acoustic pressures, etc. Excessive calculations may not be required, or previous experience may already indicate the best solution without any calculations. However, the acoustic study will have been carried out, either with complex computer simulations, with some calculations using paper and pencil, or mentally while checking the dimensions and characteristics of the premises.
The calculators we make available to our website visitors can help speed up the acoustic study, but remember...
To quickly calculate the number of speakers needed, we can use calculators that compile the usual recommendations for different types of speakers. For each type of speaker, there is a theoretical explanation and a step-by-step guide that allows you to select the enclosure, its dimensions, ambient noise, system usage, etc.
The criteria used are only a recommendation, and the user may use them or change them to whatever they consider most appropriate, taking into account the actual needs of the installation.
