Cirrus SoundSign™ - Model CR:201 - Noise Activated Warning Sign
From Signs & Indicators
The SoundSign™ is a highly visible noise activated warning sign that has been designed for use in environments where there is a need to clearly warn or indicate when a preset noise level is reached. When the ambient noise level exceeds the preset level, the SoundSign will illuminate, clearly showing the graphics and text. In addition to the traditional Noise at Work style sign, the Sound Sign is also available with a range of other graphics and text which allows it to be used in environments where the noise levels may not reach those where hearing protection is required, but where there is still a need to warn or indicate excessive sound levels.
Ideal for Noisy Environments - Show when hearing protection must be worn or when high noise levels occur
The SoundsSign is idea for use in noisy environments such as factories, workshops, pubs and nightclubs to warn when noise levels become too high and indicate when hearing protection must be worn.
When a noise survey or risk assessment has been made, areas may be found where hearing protection must be worn or where high noise levels will occur during the working day.
It may not be practical for employees to wear hearing protection constantly, especially where the noise levels are intermittent or vary significantly over the day. The SoundSign Version 1 can be used to show when hearing protection must be worn in these areas. Where hearing protection is not required but there is still a need to show when the noise levels are high, the SoundSign Version 2 would be appropriate.
If it is essential for anyone entering these areas to be prepared and already wearing hearing protection, a CR:202 SoundSign Remote Unit can be connected to the Master unit and positioned outside of the work area, next to an entrance or door for example. This will ensure that anyone entering the room will be aware of the high noise levels and the need to wear appropriate hearing protection.
A CR:203 Data Logger can be added to gather a record of when the noise levels were over the trigger level and to help monitor the effectiveness of hearing protection.
The SoundSign for Music & Entertainment
Noise levels in pubs, clubs and other entertainment venues will often be high to create the right atmosphere. However, if you have any noise limits or controls put upon you or if you are looking to protect your employees from noise exposure, then the SoundSign is the ideal product.
Lightweight and simple to use, the SoundSign can be used for temporary venues as well as for permanent installation. In music colleges and schools, the SoundSign can help to educate students as well as staff about the risks of noise exposure.
Ideal for Quiet Environments
The SoundSign can also be in quiet locations such as schools, hospitals and libraries to indicate when noise levels must be kept down.
The Version 3 and Version 4 SoundSign units can be used in these environments with different messages from those versions designed for high noise levels.
The SoundSign in Hospitals and Healthcare
Noise is often the primary cause of sleep deprivation and disturbance amongst patients and so keeping an eye on noise levels can help in the recovery process as well as help to create a calm and peaceful working environment.
Visitors and staff can be informed when the noise levels are getting above an acceptable level using the SoundSign. The SoundSign Version 4 shows an effective and clear message which can be displayed in public areas.
The SoundSign for Schools and Colleges
There have been many studies which show that high noise levels in a learning environment can affect both students and teachers. Any environment where children and students gather is likely to be noisy! Controlling noise levels can help to reduce the risk of hearing damage in young children as well as making the learning environment more pleasant.
Many buildings that are used for education were not designed with noise in mind, with hard walls and floors often creating a noisy environment with only a few students. The SoundSign can be used to show students when noise levels are getting high and also to inform staff of when problems may occur.
The SoundSign can be used in cafeterias, classrooms and corridors when examinations are in progress to help to maintain a quiet environment. SoundSign Version 4 (SHHH! Quiet Zone) is ideal for these locations.
SoundSign Remote Display Units
The Sound Sign is also available as a Remote Display Unit which is controlled by a Master Sound Sign. When the SoundSign lights up, the Remote Units light up in the same way and for the same period of time.
The Remote Display Units are connected by a simple cable to the Master and up to three units can be daisy-chained together so that a wide area can be covered.
Remote units are ideal in applications where the main unit cannot be seen. For example, in a factory where the main SoundSign is out of view of employees, a remote unit can be installed to ensure that sufficient coverage of the noise warnings is available.
Another common use for the remote units is to position one at the entrance to a high noise level environment. This can help to ensure that anyone entering this environment is aware of the need to wear hearing protection or is aware of the risk of high noise levels.
Enhance your SoundSign with a range of options and accessories
As well as the CR:203 Data Logger and the CR:202 Remote Display Units, we can provide a range of accessories and options to enhance and expand your SoundSign.
If you need to place the microphone away from the SoundSign, we can supply a range of microphone extension cables, preamplifiers and microphone capsules to allow you to put the measurement microphone up to 50m from the SoundSign.
We can also provide acoustic calibrator, a simple CR:306 sound level meter to help you set the trigger level, as well as outdoor microphones if your noise source is outdoors.
