The SV 973A is a Class 2 Sound Level Meter compliant with BS EN 61672-1:2013, designed for professional noise measurements in workplaces. With a frequency analysis in both 1/1 and 1/3 octaves, it aids in identifying noise sources. Its MEMS-based patented microphone ensures durability and extended battery life, and is backed by a lifetime warranty. The device meets Class 2 frequency response standards up to 10 kHz and operates between -10ยฐC and 50ยฐC, aligning with Class 1 temperature requirements. Its measurement range is 25 dB to 129dB, but can reach up to 141 dB Peak with its sound exposure meter function. This allows it to gauge both industrial and environmental noises, even amidst minimal background disturbance. The SV 973A provides comprehensive sound data, including LEQ, MIN, MAX, and PEAK, and integrates vital weighting filters. Enhanced with Bluetooth, it pairs with the Assistant Pro app to augment its functionality.
Class 1 and Class 2 noise meters are professional devices designed to measure sound levels with varying degrees of precision as per BS EN 61672-1:2013 standards. Though Class 1 and Class 2 meters have similar design objectives, they differ in acceptance limits and temperature operational ranges. Specifically, Class 2 meters generally have equal or wider acceptance limits than Class 1 meters based on frequency:

Class 2 Speech Transmission Measurements
STIPA, as defined by IEC 60268, measures the intelligibility of public address and voice alarm systems in large venues. The Speech Transmission Index for Public Address systems ensures that announcements remain clear in places like airports, concert halls, and shopping centers. Adhering to the IEC 60268-16 standard, the STIPA method requires a sound level meter compliant with IEC 61672-1, such as the SV 973A Class 2 Sound Level Meter. To assist in conducting STIPA measurements, the Building Acoustics PRO mobile application supports the SV 973A, offering in-depth analysis and evaluation of the system's effectiveness.
