Using the Listen Ear™ – Personal Noise Dose Meter

The Listen Ear™ – Personal Noise Dose Meter offers a new approach to Personal Sound Exposure Meters (PSEMs)

With the long term effects of noise harm now better understood and employers facing legal action for failing to provide adequate personal noise monitoring and protection, damage to hearing from noisy workplaces is governed by ever more stringent Health & Safety at work regulations in most countries.

The Listen Ear™ – Personal Noise Dose Meter provides constant personal noise monitoring of a worker’s environment and warns the wearer when they approach, or exceed their daily permitted safe dose.

Containing a Class 2 sound level meter, temperature and humidity sensors in a compact design, Listen Ear™ produces a daily report of the work environment logging Sound, Temperature, Humidity and Movement. Data is available to download as a simple text file for viewing on a PC. An optional App lets you configure, control and monitor Listen Ear™ via Mobile Application connectivity.

Listen Ear™ Unique Features

Listen Ear™ Anti-Knock & Vibration System

Anti-Knock & Vibration System

A major problem encountered with personal noise dosimeters is distinguishing between true audio impulse noise and extraneous mechanical ‘tapping’ on the personal noise dosimeter casing. The introduction of a Patented Knock and Vibration Cancelling Technology (Pat. App. 2 551 724) to the Listen Ear™ provides an additional level of accuracy to the final result. The Listen Ear™ can detect and eliminate the mechanical tapping noise, therefore the noise exposure measured and recorded is an actual representation of that environment. Number of detected ‘knocks’ is recorded and stored in the report file. The Anti-Knock & Vibration System is not active when the External microphone is connected.

Listen Ear™ SNR Settings

Simulate the effect of wearing ear defenders

If you wish to use your Listen Ear™ whilst wearing hearing protection, then this is possible by inputting the SNR attenuation figure from the specification of your hearing defender or ear plug into the instrument setup. The Listen Ear™ will take note of the new setting and give exposure readings as if measuring at your ear inside the hearing defender earmuff and not outside in the external environment.

Listen Ear™ Motion Detection

Motion detection

This feature monitors the Listen Ear™ motion status. It will detect if the unit is not worn during the recording session. The ‘non motion’ event will be detected if the unit is stationary for at least 10 seconds. Number of events and summary of ‘no motion’ time is recorded in the report file.

Listen Ear™ Mobile App

The Listen Ear™ can be controlled by an android application. The app allows starting and stopping a measurement, displaying the current measurement results and time history graph.
