The SV 104A personal noise dosimeter is designed according to IEC 61252 and ANSI S1.25-1991 (R2020) standards to ensure precise measurements. It complies with occupational noise standards such as ISO 9612, OSHA 29 CFR 1910.95, and MSHA, offering flexibility with exchange rates (2, 3, 4, 5, 6 dB) and criterion levels. The dosimeter can log essential results like TWA (Time-Weighted Average), DOSE, LEX,8H, along with Leq, Peak, SPL, Max, Min, and more.
In addition, it features options for octave band analysis and audio recording for recognizing specific noise sources. Its built-in triaxial vibration sensor helps detect false events caused by shocks or movement, ensuring more accurate readings. The SV 104A’s Bluetooth connectivity allows for remote monitoring, enabling professionals to read out results without disturbing the worker, making it a powerful and convenient tool for managing workplace noise exposure.
The Noise Dosimeter App allows users to seamlessly monitor real-time noise measurements from their wearable dosimeter directly on a smartphone or tablet. This companion tool provides a convenient, remote way to view data without needing to physically interact with the device, making it easier to manage workplace noise exposure. While the app doesn’t perform measurements itself, it displays accurate data collected by the professional-grade dosimeter. Users can also set alarms for when noise exceeds safe levels and control the dosimeter remotely, enhancing efficiency and safety without compromising measurement precision.

Key technical details include a MEMS microphone with a lifetime warranty, designed for durability and precision, even in harsh industrial environments. The microphone is resistant to shocks and drops, ensuring long-term stability and measurement accuracy. The SV 104A also offers an extensive measurement range, from 43 dBA to 141 dBA, covering a wide spectrum of noise levels encountered in various industries.
Occupational Noise
Noise Measurements for Regulatory Compliance
The SV 104A personal noise dosimeter is designed for occupational noise measurements in accordance with standards such as ISO 9612, OSHA 29 CFR 1910.95, MSHA, and ACGIH. It ensures compliance with OSHA's noise exposure regulations, which define permissible noise limits and outline the requirements for hearing conservation programs. The dosimeter accurately measures personal noise exposure levels, including the 8-hour Time-Weighted Average (TWA) of 90 dBA and the action level of 85 dBA, helping companies assess noise risks and implement effective hearing conservation measures. This makes the SV 104A an essential tool for ensuring workplace safety and maintaining regulatory compliance.
