Study interview: The effect of absorbers and screens on the decay of speech in offices

What exactly can you expect from different kinds of acoustic treatment? Which types of treatment should be prioritised and how does one treatment affect the other? In this post we interview Dr. Valtteri Hongisto about a unique and comprehensive study that provides new insights into effective acoustic design of offices. Researchers Valtteri Hongisto, Jukka Keränen […]

Irrelevant speech is a risk for your health

In offices, noise control should be a priority as unwanted sound causes stress. Continuously elevated stress levels are a health risk. Turku University of Applied Sciences and University of Turku have conducted the first Finnish medical study on the physiological, psychological, and performance effects of irrelevant speech. Office noise consists primarily of this kind of […]

Soundscapes: A perceptual design tool on the rise

How we perceive the sounds around us is dependent upon their inherent acoustic characteristics but also their associated meanings, context and our experience. We individuals shape the frame of reference. Exposure to unwanted, negative sounds (noise!) impacts our quality of life. Until now, our primary goal in acoustics has been to solely reduce the negative […]

Hospital Soundscapes and Ways to Heal Them

“The soundscape of the average modern hospital is a cacophony of overlapping beeps, blats and pings from monitors, roaring ventilation systems, raucous bursts of conversation from visitors, patients and the nursing station, carts rumbling down hallways, televisions, phones. Sleep, essential to the healing process, is available primarily through medications. Even medicated sleep can be elusive, […]

Better sound environments for doctors and nurses in the Czech Republic

One of our editors in the Czech Republic (CZ), Iveta Kralova, was recently part of an intervention study in an eye clinic in Hradec Kralove. Here follows her experience in a country where acoustic standards for healthcare are lacking and where a lot of buildings are too loud to heal. Many studies have already shown […]
