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).
