Sound Insulation/ Acoustics - Emissions


One of the most significant tasks in this field is to determine noise and vibration emissions of machines, devices and installations as well as their time elapsed, their spacious and spectral distribution and analyse them objectively.

SLG Prüf- und Zertifizierungs GmbH is appointed authority no. 0494 for the realisation of all conformance assessment procedures in compliance with article 14, 2004/14/EC Directive and DIN EN ISO 17025 for noise measurements accredited by the Federal Motor Vehicle Office.
 
Our services:

Determination of noise parameters for devices, machines and installations on site and in special measurement rooms (reverberation room, anechoic room)
 
sound power level,

psychoacoustic parameters, such as Zwicker Loudness according DIN 45631,
noise emission values at the operators position,
x values of declaration,
x weighted accleration values for human vibration,
x trigger- and exposition values,
x user-specific analysis for sound emission, sound intensity and noise source identification
Determination of acoustic parameters:
 
x acoustical absorption level of materials for vertical and diffuse sound incidence,
x

insertion loss of silencers
Analyses of products for the determination of noise and vibration causes and examinations accompanying the development and counsels during the design of silent products
