The SV 973A is a Class 2 Sound Level Meter built to the international standard IEC 61672-1:2013, and to ANSI/ASA S1.4-2014 in the United States. Its MEMS microphone is covered by a lifetime warranty. MEMS technology is very energy efficient, so the meter runs up to 38 hours on four AAA batteries. The meter works in two ranges: 25 dBA to 129 dBA for sound level measurements, and a sound exposure range that reaches 141 dBA Peak for noise at work. It operates from -10 °C to 50 °C (14 °F to 122 °F), which is the temperature range the standard specifies for class 1 instruments. The meter weighs 225 grams (7.9 oz) and measures 225 x 52 x 20 mm (8.9 x 2.0 x 0.8 in).
The SV 973A ships ready to measure and costs from EUR 1,350, depending on local taxes, duties and exchange rates.
The SV 973A costs from EUR 1,350 to EUR 2,250, or about USD 1,450 to 2,450. The range covers the instrument itself and the option packages built around it. These are list prices in euro: local taxes, duties and the exchange rate decide what you pay. Ask for a quote through the enquiry form on this page or through an authorised SVANTEK distributor.
The instrument comes with the ST 973A MEMS microphone capsule, an SC 158 USB-C cable, an SA 22 windscreen, four AAA batteries, 8 GB memory, a USB stick with the manual and a transport box. Time history logging and dose measurement are standard. Each meter ships with a factory calibration certificate and a 36-month warranty. Optional package extends it by task: P1 adds 1/1 and 1/3 octave analysis and audio recording..
Firmware functions — octave analysis, audio event recording, RT60 and STIPA — and field accessories such as a calibrator, a waterproof case, a pocket bag and a tripod can be added separately. The functions are activated with a code at any time. Accredited calibration to IEC 61672-3 is available for the instrument.
Octave filters to Class 1 of IEC 61260, and recording tied to the time history.
Three profiles at once, and a time history down to 100 ms steps.
Results and control from a phone, over the Bluetooth® 5.2 interface.
What the accuracy class covers, and where the range begins.
A second range that reaches 141 dBA Peak for noise at work.
Lifetime warranty on the microphone, and up to 38 hours of work.
Autocalibration at 94 dB and 114 dB, with drift tracked over time.
RT60 and STIPA, where a class 2 instrument is accepted.

Exposure results for OSHA, MSHA, ACGIH and ISO 9612 assessments.
For noise at work the SV 973A runs in its sound exposure range and returns the quantities an assessment needs: DOSE, TWA, SEL and peak levels up to 141 dBA. Exchange rates of 2, 3, 4, 5 and 6 dB and an adjustable criterion level cover American and European practice in one instrument. The Supervisor software calculates and reports these results to OSHA, ACGIH, MSHA and ISO 9612, and octave spectra give the data needed to select hearing protectors to ISO 4869-2. The instrument supplies the measured quantities; the assessment itself stays with the employer.

A, C and Z weighting for workshops, site boundaries and school corridors.
The SV 973A measures sound pressure level with A, C and Z weighting and with Slow, Fast and Impulse time constants, which covers most survey work: machinery in a workshop, the boundary of a construction site, a school corridor, a ventilation unit on a roof. Statistical levels L1 to L99 show how the level behaves over time instead of reducing it to a single number. The meter works hand-held or on the SA 21 tripod, and the SA 72 waterproof case protects it between measurements.

Speech intelligibility in public address and voice alarm systems.
With the STIPA option the SV 973A measures the speech transmission index to IEC 60268-16, the quantity that says whether an announcement in an airport, a station or a shopping centre will be understood. The Building Acoustics PRO app leads the measurement, keeps the results per position and prepares the report. A class 2 instrument is accepted for this measurement in part of its applications, so check the requirement in the project specification before the survey.
