Personal Noise Dosimeter
Corresponds to noise work environment measurement for occupational safety and health purposes
What is a Noise Dosimeter?
What is it used for?
Noise Dosimeter is a device that measures how much noise workers are exposed to in the workplace each working day. A compact device is attached around the ear such as the head and shoulders of the person to be measured.
Why do we need a Noise Dosimeter?
For example, in many construction sites, there is constant loud noise. People who work there are chronically exposed to noise, and their hearing deteriorates over time, leading to occupational hearing loss.
Long-term exposure to loud noise increases the risk of developing hearing impairment.
In order to protect the hearing health of workers, it is necessary to measure the noise in the workplace and take countermeasures.
Features
- Easy operation
- Simple report generation
- Compact, lightweight and wearable
How to use
Rion Noise Dosimeter
Use two buttons to start/stop measurement.
Measurement can be done in simple four steps.
Automatic sound calibration
(before measurement)
Attachment

Automatic sound calibration
(after measurement)
The alligator clip will grip firmly.
It does not come off easily even during work.
The Noise Dosimeter should be worn so that the microphone will be positioned near the worker's head, neck and shoulder. You can take measurements without worrying that the device will come off even during work that involves vigorous movement.
Press and hold the START/STOP key to start/stop measurement.
The STATUS LED flashes orange during measurement.
No operation required until measurement is completed.
Noise exposure measurement in the work environment is based on a single day. NB-14 can measure more than 12 hours on a single charge and can hold measurement data for about 48 hours.
The LED color tells you the amount of noise exposure.

The degree of noise exposure is indicated by the color of the LED light. The worker's status can be checked without going near the worker.
A mobile app that allows you to easily check the measurement results on site.
What can be checked:
- Real-time noise level measured by NB-14
- Data saved in the main unit
You can use the app by connecting the NB-14 and a smartphone with a cable.

Viewing measurement data
Measurement results report
Dedicated PC software for viewing measurement data and creating reports.
The Noise Exposure Data Management Software AS-05 Viewer loads the data measured by the NB-14 into a computer, allows you view the measurement data, and output reports that describe necessary items for the noise measurement.
It's so lightweight you will forget you are wearing it.
72g Weight of 3.5 AA batteries.
Leave the preparations for measurement to NB-14.
In order to measure the noise exposure correctly, it is important to check the equipment before and after measurement (acoustic calibration). The check is automatically completed by attaching a check device (sound calibrator) to the NB-14 microphone.
