Powerful Real-Time Analyser

Full-spectrum analysis with audio recording and fast time logging

SVAN 979 performs real-time 1/1 & 1/3 octave and FFT analysis with optional tonality, STIPA, and 1/12-octave resolution. It logs data down to 2 ms steps and supports infrasound and RT60 measurements for advanced building acoustics.

Hardware Dedicated for Professionals

Rugged construction with reinforced protection for demanding environments

Rugged construction with reinforced protection for demanding environments The SVAN 979 features a durable aluminium body with enhanced shielding against electromagnetic interference and mechanical impact. Its reinforced preamplifier and secure grip design ensure long-term reliability in field and lab conditions.

Tonality Analysis

SVAN 979 identifies tonal components and calculates annoyance penalties in decibels

SVAN 979 identifies tonal components and calculates annoyance penalties in decibels The instrument detects prominent tones in accordance with ISO 1996-2 and adds penalty values to reflect the perceived annoyance of tonal noise. This analysis supports regulatory compliance in environments where tonal characteristics affect sound quality.

Loudness Analysis

SVAN 979 quantifies perceived sound using the Zwicker method in line with ISO 532B

The device calculates loudness based on human hearing sensitivity across frequencies and provides a more accurate measure than A-weighted levels for low-level broadband noise.
