What is noise dosimeter used for?

In the UK, a noise dosimeter is primarily used for monitoring and assessing occupational noise exposure in compliance with the Control of Noise at Work Regulations 2005. It helps employers identify areas or tasks where workers are exposed to hazardous noise levels and need protective measures. The device is often used in various industries such as manufacturing, construction, and entertainment to ensure that noise levels remain within legal limits, thereby safeguarding workers’ hearing health. It can also be used in legal proceedings as evidence of compliance or non-compliance with noise regulations.

Dosimeter for noise

Personal noise dosimeter

Wearable dosimeter for noise

In the UK, a personal noise dosimeter is a specialized device worn by workers to measure their individual exposure to noise levels over a specified period. The device helps in complying with the Control of Noise at Work Regulations 2005, which aim to protect employees from hearing damage due to excessive noise exposure. Unlike stationary noise meters, personal noise dosimeters are attached to the worker's clothing and provide a more accurate representation of the worker's actual noise exposure throughout the day. The data collected can be used to assess whether protective measures, such as ear protection or changes in work processes, are needed to reduce noise exposure to safe levels.

Noise dosimetry testing

Identify noise sources with your noise dosimeter

Noise dosimetry testing is conducted to comply with the Control of Noise at Work Regulations 2005. The noise dosimeter is typically worn by workers throughout their work shift to measure their exposure to noise levels. This is an unattended type of measurement, meaning it runs automatically without requiring constant supervision. However, there are challenges such as the dosimeter being accidentally dropped or removed by workers. Advanced features like octave analysis and built-in vibration detection can identify such anomalies, making it easier to exclude them from the final noise exposure calculations. Additionally, audio recording option, helps in identifying and excluding unwanted noise sources that are not related to the work being performed, such as radio music. This ensures that the noise level data collected is as accurate as possible, aiding in the effective management of noise risks in the workplace.

Bluetooth dosimeter

Dosimeter noise monitoring app

The Bluetooth® dosimeter features a interface that allows for seamless interaction with mobile devices like smartphones or tablets. Using the Assistant Pro app, users can start and stop measurements remotely. The app also provides real-time previews of the current noise levels being recorded. Additionally, the app is equipped with an alarm feature that notifies users when preset noise limits are exceeded, offering an extra layer of safety and convenience in monitoring noise exposure.

Noise dosimeter calibration

Auto-calibration facility that simplifies the calibration process

To streamline noise dosimetry measurements, the SV 104A dosimeter features an auto-calibration function. Upon detecting a calibration signal, the device automatically calibrates itself and saves the calibration data. This data is stored alongside the measurement file, both before and after the measurement is taken. This ensures accuracy and simplifies the process, eliminating the need for manual calibration.

Vibration event detection

inbuilt tri-axial vibration sensor by BS EN 9612

In compliance with BS EN 9612, the SV 104A dosimeter comes equipped with an inbuilt tri-axial vibration sensor. This sensor is designed to detect mechanical shocks and vibrations that could potentially skew noise measurement results. It also identifies periods when the dosimeter is not in use by the worker. These events are recorded and marked in the device's time history, allowing for easy exclusion from the overall noise dose calculation. This feature enhances the accuracy and reliability of the noise measurements.

Personal noise monitoring

Occupational Noise

Control of Noise at Work Regulations 2005

In the UK, personal noise monitoring in the workplace is primarily governed by the Control of Noise at Work Regulations 2005. This regulation aims to protect workers from excessive noise levels that could lead to hearing loss or other health issues. Personal noise dosimeters are often used for this type of monitoring. These are small devices worn by workers throughout their shift to measure their exposure to noise. The dosimeter collects data on noise levels in different work environments and activities, allowing employers to assess whether they are in compliance with legal limits. The data can also be used to identify areas or tasks where noise reduction measures are needed. The device typically measures noise exposure in terms of the equivalent continuous sound level (LAEQ) and peak noise levels, aligning with British standards such as BS EN 9612.
