In our day-to-day lives, whether consciously or unconsciously, we are continuously exposed to acoustics – the science of sound – through a wide variety of hearing experiences. Our ears are always open and receive not only desirable signals but also undesirable ones in the form of noise. As surveys have shown [1], noise is among the most frequently mentioned types of environmental pollution; it is also known to be detrimental to health. Noise-induced hearing loss is only the most apparent manifestation of this problem [2].

Sufficiently accurate reference values and reliable measuring equipment are required to objectively measure and evaluate sound; both prerequisites are fulfilled due to the activities of the acoustics laboratory at METAS.  


Our measurement services encompass a wide variety of acoustic quantities and measuring equipment.

Hearing aids

METAS has been mandated by the FSIO to keep a list of all the hearing aids for which the social insurances will pay a fixed amount to the insured in accordance with the ordinances applicable (in force since 1 July 2011).
