Class 1 Dual-Channel Noise Dosimeter SV 102A+

The SV 102A+ Class 1 Dual-Channel Noise Dosimeter represents a groundbreaking advancement in occupational noise monitoring, specifically designed to meet the complex demands of the UK workplace environment. This Class 1 dual-channel noise dosimeter sets itself apart with its ability to perform detailed noise exposure assessments on both sides of the head, a feature crucial in environments where noise sources are directionally dominant or asymmetric.

In the UK, where diverse work settings range from bustling urban construction sites to precision-demanding military and aerospace sectors, the SV 102A+’s dual-channel technology offers an unparalleled advantage. By utilizing two microphones, the dosimeter can simultaneously measure noise exposure at both ears, providing a more accurate representation of the auditory challenges workers face.

MIRE Technology: Advancing Noise Measurement Standards

The SV 102A+ goes a step further with its MIRE (Microphone In Real Ear) technology, compliant with ISO 11904 standards. This innovative approach is crucial for settings where noise sources are near the ear, such as in call centers or under pilot helmets in military aircraft and tanks. MIRE technology is also instrumental in assessing the real-world effectiveness of hearing protection devices, making the SV 102A+ an essential tool for industries focused on auditory safety, including those adhering to stringent aerospace standards set by organizations like NASA and ESA.

In line with the UK’s Control of Noise at Work Regulations 2005, the SV 102A+ not only ensures compliance with legal requirements but also advances the standard of workplace noise monitoring. Its sophisticated features cater to the nuanced needs of UK industries, offering a robust solution for accurately assessing and managing noise exposure risks.

Microphone in Real Ear: Precise Noise Exposure Analysis

The SV 102A+ employs the innovative ISO 11904-1 MIRE (Microphone in Real Ear) measurement technique, a critical tool for accurate noise exposure assessment in specialized UK work environments. This advanced method involves capturing sound directly at the ear canal using the specialized SV 25S microphone probe. This approach is particularly effective in situations where traditional dosimetry is insufficient, such as in UK call centers where noise originates from headsets. By performing detailed one-third octave band analysis, the SV 102A+ provides a comprehensive and accurate assessment of noise exposure, ensuring compliance with UK workplace noise regulations. The integration of MIRE measurements necessitates the use of the SV 25S MIRE microphone along with 1/3 octave analysis capabilities.

Class 1 Precision for UK Noise Monitoring

Combining Noise Dosimeter and Sound Level Meter Capabilities

Adhering to the stringent standards of BS EN 61672-1, the SV 102A+ stands out as a highly precise noise monitoring solution suitable for the diverse requirements of UK workplaces. It functions both as a Class 1 noise dosimeter and a sound level meter, ensuring accuracy even under challenging conditions. This includes operating in extremely low temperatures (down to -10°C) and in environments where noise is predominantly high-frequency, in line with the recommendations of BS EN ISO 9612. The SV 102A+ operates at a high sampling rate of 48 kHz, guaranteeing precise and reliable noise level readings critical for maintaining UK workplace health and safety standards.

Dual-Channel Input for Comprehensive UK Noise Assessment

Class 1 Measurements with Dual Microphone Capability

The SV 102A+ is uniquely equipped with two input channels, allowing for the simultaneous use of two microphones. This dual-channel feature is pivotal for UK workplaces, as it facilitates the placement of microphones on both sides of a worker's head, ensuring a comprehensive assessment of noise exposure. In addition, by incorporating the MIRE microphone technology, the SV 102A+ can be configured with one microphone positioned on the shoulder and another inside the ear. This setup is particularly beneficial for assessing the effectiveness of hearing protectors or headsets, such as those used by military pilots, providing a detailed verification of attenuation in various noise-intensive environments across the UK.
