Room Type Acoustic Design Guides
Comprehensive acoustic design guidance for 12 room types. Each guide covers RT60 targets, applicable standards, material recommendations, common failure modes, and FAQs based on published acoustic standards.
Classroom
Typical volume: 150-300 m³
Classrooms are the most acoustically critical room type in education buildings, where speech intelligibility directly determines learning outcomes. A well-designed classroom achiev...
Open Plan Office
Typical volume: 400-600 m³
Open plan offices present a unique acoustic paradox: speech must be intelligible within conversation groups but unintelligible beyond the distraction distance to preserve privacy a...
Meeting Room
Typical volume: 60-100 m³
Meeting rooms require controlled reverberation for clear face-to-face and video-conference communication. The small volume and hard glass partitions common in modern offices make t...
Concert Hall
Typical volume: 6,000-10,000 m³
Concert halls represent the pinnacle of acoustic design, requiring simultaneous optimisation of seven ISO 3382-1 parameters. The target RT60 of 1.8–2.2 seconds for symphonic music ...
Hospital Ward
Typical volume: 250-350 m³
Hospital wards must balance patient recovery needs with staff communication requirements. Excessive noise is linked to disrupted sleep, elevated stress hormones, and slower healing...
Restaurant
Typical volume: 300-500 m³
Restaurant acoustics must balance conversation intelligibility with ambient atmosphere. Excessive reverberation triggers the Lombard effect, where diners progressively raise their ...
Residential Living Room
Typical volume: 50-70 m³
Residential living rooms require low reverberation and quiet background conditions for comfortable speech, media listening, and relaxation. Modern open-plan living spaces with hard...
Worship Space
Typical volume: 2,000-4,000 m³
Worship spaces present the highest acoustic design complexity because speech and music have fundamentally conflicting reverberation requirements. Speech intelligibility demands RT6...
Library
Typical volume: 150-250 m³
Libraries require ultra-low background noise for focused study while managing acoustic zoning between silent reading areas, collaborative zones, and public spaces. The target RT60 ...
Cinema / Theatre
Typical volume: 1,500-2,500 m³
Cinemas and theatres require short reverberation times (0.8–1.2 seconds) to preserve dialogue clarity and allow the soundtrack’s engineered reverberation to be heard accurately. Ba...
Gymnasium
Typical volume: 1,500-2,500 m³
Gymnasiums are among the most acoustically challenging room types due to their large volume, all-hard surfaces, and requirement for both physical activity and verbal instruction. U...
Recording Studio
Typical volume: 60-100 m³
Recording studios demand the most stringent acoustic control of any room type. The control room requires an RT60 of 0.2–0.4 seconds with a flat frequency response for accurate moni...
