Adaptive room acoustic design
(2020) MMKM05 20201Innovation
- Abstract
- This report summarizes the methodology, development and results of a master thesis regarding the design of an adaptable acoustic panel. When a room gets acoustic treatment it’s usually fitted with one activity in mind, such as a conference room or an office space. Multipurpose rooms tend to perform good for a few set of situations and underperform for the vast majority. For example, in a classroom full of toddlers the absorption has to be maximized to dampen the noise, but if the same room is used for speech that much absorption would impair it. Some reverberations in the room are useful to carry the speech to the listeners and give some feedback to the speaker.

When a room gets acoustic treatment it’s usually fitted with one activity in mind, such as a conference room or an office space.

For example, in a classroom full of toddlers the absorption has to be maximized to dampen the noise, but if the same room is used for speech that much absorption would impair it. Some reverberations in the room are useful to carry the speech to the listeners and give some feedback to the speaker.
The purpose of the thesis is to build a prototype of an adaptable acoustic panel that can modify the acoustic properties of a room to obtain different acoustic environments. The panel would be installed in a wall and it would redirect the incident sound to different angles to obtain different acoustics properties. This way a multipurpose room can fit a variety of activities while maintaining good acoustics.
A full scale prototype was developed, both its hardware and software. When it was functional two experiments were carried out to analyse its behaviour. The first one, in a reverberant room, where reverberation time and speech clarity were measured for different configurations of the panel. A noticeable difference in the room acoustics was generated with the topology changes of the panel. The second one, in a semi-anechoic chamber, where the scattering of the sound was measured for multiple setups. The panel behaves as it was intended for higher frequencies, where speech is located.
