Acoustics for stores and shopping centers

Public Address systems

Public Address systems are a class of acoustic equipment specifically designed to sound public spaces: shopping areas, train stations, airports, etc. In fact, it is a set of medium-power loudspeakers, amplifiers and mixers.

Purpose:

Speakers installed evenly around the perimeter of the room or along the aisles of the mall, voicing the space
Amplifiers are needed to increase the level of the original signal
Mixers allow you to switch the sound from different signal sources and adjust the volume. They can also be used to lower the volume of background music, for example, to make a voice announcement.

How to choose a speaker system for the mall

There are a number of factors to consider when choosing speakers:

The frequency range of the speakers should be wide enough and the power should match the volume of the room
Power amplifiers should provide operation in 24/7 mode
It is preferable to make a set of mixer-amplifier-speakers from the equipment of one manufacturer and other requirements
When choosing acoustic equipment, to ensure good and clear sound, it is better to proceed from a special acoustic calculation of the room (the shape of the room, finishing materials, height and orientation of the sound systems to be installed are taken into account)
