Sound impact, sound quality
Acoustics
| Measurement | Sound impact, sound quality (e.g. loudness, annoyance, performance) |
| Standards | ISO/TS 15666, ISO 16832, etc. |
| Methods | Interviews, perception and performance tests (users, affected people, test persons) |
Technical data
| Floor area | 44 m2 |
| Room volume | 132 m3 |
Special features
| Acoustics | Room acoustics: variable reverberation time by using removable absorptive ceiling and linings Electroacoustic system: 64 channel sound field system (IOSONO) comprising 412 loudspeakers for realistic presentation of acoustic scenarios, laboratory and software for production of sound files, studio for 4 test |
| Light | Daylight: light wall for sunlight simulation in front of the façade (luminance up to 10 000 cd/m², colour temperature between 3000 and Inside: highly variable artificial lighting with DALI bus system, e.g. for adaptive light management |
| Ventilation | Ventilation rate 300 to 1800 m³/h Room temperature between +18 and +30 °C |
More information
- Identification of sound impact and optimization of sound quality of products or components in buildings, e.g. building service systems and installations
- Investigation of use-related room scenarios, e.g. offices, meeting rooms and classrooms, with test persons in order to quantify room influences on well-being and performance
