Ocena jakości akustycznej pomieszczeń biurowych typu open space z uwzględnieniem normy ISO 22955:2021
Evaluation of the acoustic quality of open plan offices spaces, taking into account the ISO 22955 standard

Summary/Abstract: The Polish standard PN-B-02151-4: 2015 distinguishes two types of large-area work rooms: 1 – open plan offices, operating rooms for banks and offices, customer service offices and 2 – call centres. In each of these types, criteria for the minimum sound absorption of the room are defined. The PN-EN ISO 3382-32012 specifies four other acoustic criteria for rooms, but referring only to rooms type 2. For workplaces or the above-mentioned the rooms are also subject to the criteria for permissible noise specified in the PN-N-01307:1994 and the PN-B-02151-2:2018 standards. Above the criteria were developed from 28 to 4 years ago and in many cases are not fully adapted to the currently used rooms. As a result, the new ISO 22955: 2021 introduced a new division of open plan offices spaces/rooms. There are five types of used rooms and an additional class i.e. a room intended for office work, but without equipment. The article will discuss the acoustic requirements and the evaluation criteria of the rooms according to ISO 22955:2021 and the standards: PN-N-01307, PN-B-02151-2, PN-B-02151-4 and PN-EN ISO 3382-3.
