This noise warning sign is there all the time so you don't have to be! These health and safety warning signs are ideal for use in environments where there is a constant need to monitor safe noise levels. The PulsarSafeEar noise activated warning sign is perfect for use in factories, workshops, pubs and nightclubs as a hearing protection sign to alert workers in real time when background noise levels are too high and hearing protection must be worn.

  • In environments where the wearing of hearing protection may not be required at all times, the PulsarSafeEar noise activated warning signs act as hearing protection signs to inform employees when Personal Protective Equipment is required and also when it can be safely removed.
  • The PulsarSafeEar can also be used in quiet locations such as offices, call centres, classrooms/exam rooms, corridors, hospitals and libraries to indicate when high noise levels must be kept down or to create quiet zones. Simply set the PulsarSafeEar to trigger at a low-level noise to ensure that noise levels in quiet environments stay within acceptable levels.

Remote display units:

Connect your Master Pulsar SafeEar to additional Remote SafeEar Display Units; the SafeEars can be daisy-chained together to cover a larger area and so more people can see it. Using this method they can also show different noise alert messages in various languages to cater for a workforce made up of a diverse ethnic mix. 

Four standard noise warning sign designs available

  • Hearing Protection Must Be Worn
  • Safety signs: Warning High Noise Levels
  • Caution sign: Caution High Sound Levels

PulsarSafeEar reporting software

Capture and store noise level measurements easily: The PulsarSafeEar can be upgraded to become a data logging unit for capturing and storing noise measurements by adding the PulsarSafeEar Data Logger and USB Software. The Data Logger simply plugs into the PulsarSafeEar and can record noise levels over long periods of time. The Data Logger can be programmed to start recording at a specific time and date and run, for example, over an 8 hour shift.

When plugged into a PC the software will display a graph of the recorded noise levels and allow the data to be printed, exported and annotated for reference.

Pulsar SafeEar Remote Units

The PulsarSafeEar is also available with additional remote display units which are controlled by the Master Unit to inform workers of high noise levels in the workplace. A simple cable from the Master Unit can control up to 3 Remote Units by daisy-chaining them together so that a wide area can be covered.

Flashing warning beacons

Choose to add a high visibility flashing warning beacon in Red or Blue to your SafeEar Master to make it even more obvious to your employees and visitors when your pre-set noise levels have been exceeded and hearing protection must be worn. The flashing beacon is triggered automatically when the Pulsar SafeEar noise-activated warning sign lights up in warning.

We have a test area where the noise is occasionally above 84dB. As such, we need to warn staff and visitors alike before they enter the building of the potential danger. We looked at the Pulsar SafeEar and thought it was ideal for our purpose. We decided to locate the master board at the entrance of our test bed. The sign was easy to install and easy to set up. The Pulsar SafeEar noise activated warning sign is benefiting the people who are operating and visiting this area, advising and warning them to the potential exposure to noise. We are happy to recommend this product to other customers with similar noise measurement needs.
Chesterfield College of FE
Chesterfield College of FE has become the first in education to install a noise-activated warning device by Pulsar in their workshops. Paul Lowry, health and safety officer at Chesterfield College, said: "Until now, we have had to rely on random noise testings in areas such as auto workshops, engineering, silversmith and brick workshops. But PulsarSafeEar is really simple, accurate and visual. As soon as noise levels in the workshop goes over the legal limit, the sign flashes on the wall and teachers and students can immediately see they need to wear protection."We see the PulsarSafeEar as a teaching aid for learners. They plan to pull this device into the lesson to make the point about variable noise and when protection is and isn't needed." Shaun Smith is a team leader and engineering technician at the college. He said: "We have installed two units in our vehicle refinishing shop. The design is really eye-catching and easy to use. The students notice when it lights up and they can see how a sharp noise is as damaging as a prolonged sound."

As part of my MSc dissertation in critical care at Cardiff University, I aimed to reduce noise levels on an intensive care unit, to enhance sleep quality and reduce the incidence of delirium. A Pulsar SafeEar Noise Warning Sign was placed within each individual bed space, following the activation of the warning signs, quiet time noise reduced by 3 dBA and night time noise reduced by 4 dBA. This reduction in noise levels also reduced the incidence of delirium by 8.1% from the previous year. These results highlight the importance of these visual prompts to try and remind staff and visitors to reduce noise levels.

The customer care we received from Pulsar was excellent, everybody in the team we spoke to was very professional and helpful and went way and beyond what was expected. Simon, the sales manager was also pivotal in helping me understand the logarithmic decibel scale.

I can not thank the team at Pulsar enough.

Bought two of these signs to put up in the engineer workshop on site. These signs are an excellent visual warning. The sign is very bright and clear when activated.

We are very happy with our purchase of the SafeEar system and has proven to be an effective way of controlling the hearing protection of our staff without forcing them to permanently wear ear protection.
