Acoustics
Experiences and testing facilities
Sound map as the result of a microphone array measurement at a passing locomotive
Sound map as the result of a microphone array measurement at a passing locomotive		 We also have a wide range of experience in the field of acoustics. Successfully processed projects reach from hearing aids to household appliances, construction machines, vehicles of all kinds and ship engines. Sulzer Innotec has one of the largest acoustic laboratories in Switzerland including an anechoic room (50 m2), a reverberation chamber and a facility to measure acoustic transmission. A large stock of measurement equipment enables us to perform experiments in the laboratory, at the customers test facility or in the field.
Measurement of sound level and sound intensity; localization of sound sources
Measurement with a microphone array for identification of noice sources at vehicles at full speed
Measurement with a microphone array for identification of noice sources at vehicles at full speed		 We offer measurements of sound level and sound intensity with weighting according to relevant standards.

Development of recommendations and countermeasures
Our aim is to measure, analyse and interpret the results in order to derive recommendations to solve the existing problems. Thanks to our extensive knowledge in machinery danymics we are able to develop optimal solutions to eliminate noise problems at the source, rather than simply install bulky noise barriers. In addition to experimental methods tools for numerical simulations are als available.
