THOUGHTS ABOUT OPEN PLAN SPACES STANDARD 3382-3

Valtteri%20Hongisto.jpg

This is an interview with PhD Valtteri Hongisto, Senior Research Scientist at the Finnish Institute of Occupational Health and Adjunct Professor at Helsinki University of Technology.
He has performed a lot of acoustic research and has been involved in the creation of standards and guidelines, for example the Acoustic Classification of Spaces in buildings SFS 5907. Also he is one of the writers of the coming Finnish Classification on indoor climate.

Valtteri mentioned that the ISO standard 3382-3 will only deal with open-plan office acoustics and not with open plans in general, like in schools, libraries or hospitals. The focus will be on spacial attenuation and speech intelligibility. By doing that we can judge the performance at any distance from the speaker.

Listen to the interview (3,47 minutes).

Alarms in hospitals – a chaotic sound environment

The use of alarms in hospitals was discussed intensively during the two days session "Healthcare Acoustics & Speech Privacy".

A study presented by S. Okcu, College of Architecture, GaTech, states that a patient in an ICU can be surrounded by up to 33 different alarms from medical equipment. Not only are the alarms disturbing to the patients, they also make the task for the staff to detect and analyse them more demanding.

"The alarms are of utmost importance, but do we really need all these alarms?" This is a question asked by Dr. Busch-Vishniac, MacMaster University (formerly from Johns Hopkins University) who was one of the presenters at the conference. And the question is relevant; in nine out of ten times no action is taken when an alarm goes off, except for turning the alarm off.
