Sound and public address systems

Sound systems

They are everywhere - casual music in the restaurant, energetic rhythms in the gym, advertising messages in the supermarket, themed radio in the office or relaxing tunes in the spa. Modern sound solutions follow two main directions – public address systems and background sound.

In recent decades, special attention has been paid to human safety. Public address systems are indispensable here. In case of emergency situations, fast and efficient evacuation from public buildings, metro stations, industrial premises, hotels, etc. is achieved through voice instructions.

The big stake

Standards for the design, implementation and maintenance of public address systems have been introduced with the purpose of saving lives. The products themselves have to meet detailed requirements too. The main ones are: priority of voice messages over music, power and power supply redundancy of the systems, monitoring of the operability of all components of the system.

Speakers come in different shapes and specifications depending on their intended function: for the lobby of a large hotel are the designer’s solutions for high quality sound; for halls and parking lots - the industrial type of loudspeaker. Regardless of the type, their task is the same - to achieve high comprehensibility and even distribution of sound pressure.

One site needs music, another one requires a public address system complying with strict regulations and so on. There may be several solutions for a site but what ANDY’s experienced professionals will offer its customers is the optimum solution for each case.
