About the Svantek SVAN 977A
As a sound level meter instrument, the Svantek SVAN 977A is designed for demanding applications. Specifically, sound level meters measure environmental and occupational noise levels in decibels with frequency weighting and time averaging per IEC 61672 and ANSI standards. Accurate and reliable performance is essential — measurement drift or component failure can cause costly errors, compliance issues, and project delays.
