ISO 23591 specifies differentiated criteria for acoustic conditions and characteristics for rooms and spaces used for music rehearsal. The criteria are specified for different types of music, regardless of the type of building in which the spaces are located.
ISO 23591 provides criteria for room acoustics in spaces used for music rehearsal, whether this is the primary use of the spaces or they are multipurpose spaces. Together with the acoustic criteria, requirements are given for net room height, net room volume and net area. Criteria for acoustic conditions are differentiated on the basis of three music types: amplified music, quiet acoustic music, and loud acoustic music.
ISO 23591 is applicable to the planning of new buildings and the refurbishment of existing ones. It can also be used to assess the suitability of existing spaces for different musical purposes. It can be used for the adjustment of rooms and spaces whose primary purpose is not music rehearsal such as sports halls, classrooms, assembly halls, multi-purpose rooms, etc. Flexible acoustic solutions can be used in order to cover several purposes of use.
NOTE-
The criteria in ISO 23591 do not apply to large, specialized concert halls, opera venues and similar spaces which are basically designed for concerts and performances, or specialized music recording studios.
ISO 23591 does not deal with the need for logistics, storage rooms for instruments and other key support functions relating to music rehearsal. Sound insulation criteria are not included in ISO 23591.
ISO 23591 on acoustic quality criteria for music rehearsal rooms and spaces is useful for:
The acoustic properties of a room are crucial for the interaction between the room and the musical instrument. When the acoustic response of a room works well with the instrument, good conditions are achieved for both audience and musicians. There is a clear connection between the intended use of a music room, the type of music, the ensemble type and the size of the room.
ISO 23591 describes criteria for any kind of rooms and spaces used for music rehearsal. The rooms used for music purposes vary from small practice rooms for one or a few musicians to very large rehearsal rooms and concert halls. In large concert halls, skilled acousticians are engaged in designing and planning acoustics. In the practice rooms and rooms used for rehearsal or more unformal music performances, the acoustic environment is often not suited for this purpose.
ISO 23591 helps you determine the sound pressure level at the forte applying the sound strength of the room and the average sound power level at the forte of the musical instruments. This leads to a favourable range of net room volume and reverberation time for a certain ensemble type. it also provides guidelines concerning your processes for the planning of rooms for music rehearsal.
