Illuminated noise warning signs to warn of excessive sound

SoundSign noise warning sign [noise warning signs]

Cirrus Research is a leading manufacturer of noise warning signs.

The SoundSign is a noise warning sign designed to activate when noise levels are exceeded. Different graphics and text warn the user when noise levels have been met. Action can then be taken.

Noise warning signs are ideal for noisy environments, particularly where hearing protection must be worn. The SoundSign also provides graphics that are suitable for quiet areas such as schools and hospitals.

The noise warning sign is available as a remote display unit, which means that it can be extended for use in larger areas.

SoundSign noise warning signs for noisy environments:

The SoundSign is ideal for noisy environments such as factories, workshops, pubs, and nightclubs. The noise warning sign can warn the user when noise levels are too high and hearing protection must be worn.

The “hearing protection must be worn” is suitable in areas where hearing protection must be worn. “warning! high noise levels” is suitable in noisy areas where hearing protection is not required.

A SoundSign remote unit can be used to warn anyone entering these areas that they will need to take the appropriate precautions.

Remote SoundSign noise warning signs:

SoundSign remote display units warn users in the same way as the main unit. This feature is ideal in applications where the main unit cannot be seen. The visibility of the noise warning sign is increased.

The main unit and remote display units are connected by a simple cable.
