What is noise dosimeter used for?

A noise dosimeter is used for measuring and monitoring noise exposure levels in work environments, and when designed to be intrinsically safe, it adheres to UK regulations such as the Control of Noise at Work Regulations 2005, as well as international standards like ATEX and IECEx. Specifically tailored for hazardous settings like mines and petrochemical plants, the device ensures compliance with these stringent safety regulations. It continuously records noise levels over a designated period, providing an accurate assessment of an individual’s exposure to potentially harmful noise. This data is crucial for implementing safety measures that protect workers’ hearing and overall well-being.

Personal noise dosimeter

ATEX and IECEx certification

Intrinsic safety (IS) is crucial for ensuring the safe operation of electrical equipment like the SV 104BIS personal noise dosimeter in hazardous environments, as it minimises the risk of ignition caused by electrical or thermal energy. The SV 104BIS adheres to the ATEX directive and IECEx certification scheme, which are stringent standards designed to regulate equipment used in potentially explosive atmospheres. By limiting the energy available for ignition, the device can safely operate in high-risk areas such as mines, petrochemical plants, and other industrial settings where flammable gases or dust are present. Intrinsic safety ensures that the equipment will not become an ignition source, thereby safeguarding both the workers and the facility. This level of safety is essential for compliance with occupational health and safety regulations, and it provides peace of mind for both employers and employees. The ATEX and IECEx certifications serve as a guarantee that the device meets international safety standards, making it a reliable choice for noise monitoring in hazardous conditions.

Best noise dosimeter

Hardware features

The new SV 104 BIS is considered one of the best noise dosimeters due to its advanced features, which include a new MEMS microphone, an expansive measuring range, large 8GB memory, and fast data transmission capabilities via a new docking station. The MEMS microphone provides a measuring range from 53 dB Leq to 143 dB Peak, allowing for highly accurate and comprehensive noise level assessments across a wide range of environments. This broad measuring range is particularly beneficial for capturing both low and high noise levels, making the device versatile and suitable for various industrial settings.

Noise dosimeter software

Options for noise sources recognition

The large 8 GB memory enables the SV 104BIS to record 1/1 or 1/3 octave bands in real-time and simultaneous audio recording. The 1/1 octave analysis is often used for the selection of hearing protectors. The 1/3 octave function allows the determination of the influence of high or low frequencies on overall values. Audio recording is synchronized with a noise time-history and it can be opened and played back in PC software enabling noise source recognition.

Noise dosimeter app

Remote connection via Bluetooth® interface

The software accompanying the SV 104BIS noise dosimeter capitalises on the device's large 8GB memory to offer advanced features like real-time recording of 1/1 or 1/3 octave bands, as well as simultaneous audio recording. The 1/1 octave analysis is particularly useful for selecting appropriate hearing protectors, as it provides a comprehensive overview of the noise spectrum to which workers are exposed. This helps in choosing hearing protection that is most effective for the specific frequencies present in the work environment. The 1/3 octave function, on the other hand, allows for a more nuanced understanding of how high or low frequencies influence overall noise levels. This is crucial for identifying specific noise sources that may require targeted noise control measures. The software also enables audio recording to be synchronized with a noise time-history. This feature is invaluable for noise source recognition, as it allows safety professionals to play back the audio on PC software and pinpoint the exact sources of harmful noise levels.

Measurement accuracy

BS EN 61252 and BS EN 61672 standards

The SV 104BIS noise dosimeter's measurement accuracy is in compliance with BS EN 61252 and BS EN 61672 standards for Class 2 sound level meters, ensuring that it meets stringent criteria for precision and reliability. These British standards are widely recognized benchmarks for the performance of sound measuring instruments. The device is also suitable for noise exposure measurements in accordance with BS EN 9612, another key standard that outlines methodologies for determining occupational noise exposure. The SV 104BIS features time history logging capabilities, recording key metrics such as Leq (equivalent continuous noise level), Max (maximum noise level), Min (minimum noise level), and Peak levels. These metrics are logged in two simultaneous steps and saved in the device's internal memory. This allows for a comprehensive and nuanced understanding of noise exposure over time, which is crucial for effective occupational health and safety planning.

Auto-calibration

automatic start of calibration

The SV 104BIS noise dosimeter features an auto-calibration function that simplifies the process of noise dosimetry measurements. Once the device detects a calibration signal, it automatically calibrates itself and saves the calibration data along with the measurement file. This occurs both before and after the measurement is taken, ensuring consistent accuracy throughout the monitoring period. The importance of this auto-calibration feature lies in its contribution to both ease of use and data integrity. Manual calibration can be time-consuming and prone to human error, whereas auto-calibration eliminates these issues, making the device more user-friendly. Additionally, by saving the calibration data with the measurement file, the SV 104BIS provides a complete and traceable record of each measurement. This is crucial for compliance with occupational health and safety regulations, as it allows for transparent auditing and verification of the data.
