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?
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 […]
A good hospital is well built!
The population is aging, we are living longer and new methods of treatment are constantly emerging. Growth is sought in the productivity of nursing care and the skills it requires will be more demanding. This creates pressure to build resilient, functional, and technology-efficient hospital buildings with a long technical lifespan. Good facilities, their indoor climate, […]
Acoustic standards in hospitals – overview and thoughts
This is the world – we need acoustic standards! The Danish Cancer Foundation has concluded that traffic noise can lead to breast cancer and non-Hodgkins lymphoma. The Danish Ministry of Environment concludes that 500 Danes die every year because of traffic noise – because of diabetes, stress, and cardiovascular diseases caused by noise. The Danish […]
Acoustic measurements: affects on cognitive testing of patients
To investigate what impact room acoustics have on staff and patients an intervention study with acoustic measurements was done in a dementia clinic in Århus, Denmark. The study was part of a BA project at The Technical University of Denmark[1]. The room that was used for the study was an office where the doctors do […]
Acoustics affect staff in the OR
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
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 […]
Short reverberation time in critical care is not enough
Short reverberation time does not do the whole trick in healthcare facilities, it´s the peaks that will wake the patients up! Out of our comfort zone When we are sick and feel bad – we seem to forget that just opening the door to a hospital makes us out of our comfort zone. Our system […]
Hospitals. Noise. Sleep. Finally an acoustic standard!
New acoustic standard for hospitals in Denmark This year a new acoustic standard for hospitals will be approved in Denmark. Up until now there has only been some rough guidelines (not mandatory). The acoustic demand will be on reverberation time. The value will be 0.6 sec. in e.g. patient rooms, examination rooms and corridors. There […]
Input data – how do we predict room acoustics?
Calculation tools Recently a new acoustic calculation tool has been published. It is based on Air Flow Resistance (AFR) and calculates several room acoustic descriptors. This article aims to explain why calculations based on the Sabine equation are not always the whole truth. Background – Sabine and ISO 3382-1/2 A long tradition of research shows […]
