Howard Leight by Honeywell Quietdose personal dosimeter

The Quietdose personal dosimeter from Howard Leight by Honeywell is designed to assist in workplace hearing conservation programs.

According to SafeWork Australia, an estimated 1 million Australians are exposed to hazardous levels of noise at work at a cost of at least $30 million annually in compensation payouts alone. Studies show that noise exposure is the most common cause of occupational hearing loss and that most hearing loss occurs in the first 5-10 years of exposure. The Quietdose is designed to deal with this problem before it occurs.

The Quietdose is an ‘in-ear’ dosimetry device that measures the noise that workers hear accurately and in real time. By avoiding costly engineering changes and accurately measuring noise exposure at its source, employers can make significant savings and take steps to adjust workers’ hearing protection.

Traditional dosimetry devices measure the ambient noise around the worker and then make assumptions or estimates about the sounds that impact the wearer’s ear. Quietdose measures the actual noise hitting the wearer’s eardrum. It is essentially a hearing protector that measures itself, taking the guesswork out of traditional dosimetry by providing truly accurate data that can be used to adjust hearing protection immediately.

The data allows supervisors to respond when an alarm is activated if the worker is getting close to the safe noise limit. The Quietdose measures the ‘dose’ of noise a worker is hearing over the course of the day and can be programmed to send an SMS or email alerting the supervisor if workers are being overexposed to noise.
