This research carried out by University of Bremen ISF – Institute for interdisciplinary School Research into the impact of improving ventilation was based on previous studies (Bremen III) […]

Combination of Absorbers and Diffusers – An Experimental Study in a Classroom

2020-09-22 by Colin Campbell

This study provides information on how different acoustic treatments can be used to obtain different room acoustic qualities, and can be used to improve and fine-tune the room acoustic parameters for better speech and listening conditions in classrooms. The background overview The most common acoustical treatment in ordinary classrooms is a suspended sound absorbing ceiling. […]

Great acoustics in operating rooms!

2020-06-03 by Maria Quinn

Noise in hospitals Noise levels have steadily increased in hospitals over the last >40 years, both daytime and nighttime [1]. The noise level in operating rooms can be particularly difficult and research shows that this may affect the ability of the staff to perceive proper oral instruction; it also affects their perceived stress and well-being. […]

Diffuse sound fields in healthcare facilities?

2020-04-22 by Mai-Britt Beldam

Diffuse sound fields – calculate right! Some years ago Saint-Gobain Ecophon published a new tool for calculating room acoustics. The tool makes it possible for the user to see both Sabine calculations on reverberation time, speech clarity, and room gain. It makes it possible for the user also to see calculations based on air flow […]

Acoustics affect staff in the OR

2019-01-21 by Mai-Britt Beldam

Introduction Sustainable working environments include good room acoustics but working in and operation room (OR) can be a challenge. Due to hygiene regulations and demands the surfaces are often hard and reflective and this leads to high sound pressure levels, bad speech clarity and long reverberation times. The Study At Hvidovre Hospital in Copenhagen, Denmark […]

Bad acoustics – higher pulse, more medication

2018-10-23 by Mai-Britt Beldam

Healthcare and sound Some of us have tried to be sick in a hospital – most of us have tried to be relatives to a sick person in a hospital – and all of us have been affected by sound. Sometimes we are aware of it – sometimes we suffer without knowing it. This following […]
