SV 102A+ is a Class 1 dual-channel noise dosimeter for complex environments where exposure differs ear-to-ear or under headsets. Two independent channels let you measure under a headset and at a reference position (e.g., shoulder) at the same time, or left/right near-ear simultaneously, capturing asymmetric exposure without repeat shifts. It reports compliance metrics including Dose (%), TWA8h, and LEX,8h / LEP,d for OSHA/ISO-style programs. Ships ready to use with core accessories for immediate deployment.
For MIRE (Microphone-in-Real-Ear) assessments under headsets/helmets, the SV 102A+ supports ISO 11904-1 methods. MIRE requires the optional SV 25S in-ear microphone and enabled 1/3-octave bands to recalculate doses from in-ear levels. A high 48 kHz sampling rate preserves close-to-ear transients and high-frequency content. Investigations are accelerated by audio recording (for playback and source verification) and 1/1-octave analysis for hearing-protector selection. If you need a single-channel wireless model, the SV 104A adds Bluetooth® for app-based monitoring; for hazardous areas, SV 104IS kits are available.

Class 1 Noise Measurements in the Workplace
Occupational noise dosimetry, aligned with standards such as ISO, OSHA, and NIOSH, is key to protecting workers from harmful noise. The challenge of accurately measuring noise exposure comes from its variable and multi-directional nature in the workplace. The SV102A+ Dual Channel Dosimeter addresses this by allowing simultaneous noise measurements from different directions with a single device, making the process more efficient and less intrusive for workers. In environments like aviation or call centers, where noise sources are complex, traditional dosimetry methods may not be sufficient. The Microphone in Real Ear (MIRE) measurement technique is critical here. MIRE provides a direct assessment of noise exposure at the ear, leading to a more accurate understanding of auditory risks. Additionally, the SV102A+ facilitates unattended noise dosimetry with audio recording and frequency analysis features. These are important for analyzing noise sources after measurement, helping to identify specific noise contributions and develop effective mitigation strategies.
