Noise Dosimeters

The doseBadge was the world’s first wireless noise dosimeter and has continued the lead marketing since it was launched in 1990s. It is the ideal solution for measuring individual exposure to noise. Combining innovative design with ease of use, it is reliable, robust and comfortable enough to wear for the duration of a shift, weighing only 1.7 ounces.

The doseBadge can be worn in areas where the microphone cable ancient dosimeters represents a risk to the wearer. No buttons or screen, it is not possible to interfere or tamper with the noise measurements. The doseBadge is powered by a rechargeable battery, incorporates an internal microphone and has an advanced electronic system that measures and records the noise levels.

Environmental Noise Monitors

If you need to monitor environmental noise, an outdoor noise measurement kit partnered with the Optimus+ Green sound level meter is the ideal solution. Using the internal modem in the CK:690 kit allows the Optimus+ to communicate with our license-free NoiseTools software remotely over a 3G/GPRS connection. It also allows for alerts to be sent directly to you via SMS, email and/or Twitter when the Acoustic Fingerprint™ detection triggers are reached or exceeded.

If if you require a more permanent noise monitoring solution, then our environmental noise monitors are ideal.
