Acoustic design of schools: performance standards

23 May

Acoustic Panels for Education Facilities

In the UK, the acoustic regulations for schools are primarily detailed in Building Bulletin 93 (BB93), which outlines the minimum performance standards for the acoustic design of school buildings. These standards are essential to create a learning environment that supports clear communication and minimises noise distractions.

Key aspects of BB93 include:

Indoor Ambient Noise Levels: Classrooms and other learning spaces must adhere to specified maximum noise levels to maintain a quiet environment. For example, the maximum indoor ambient noise level in a classroom during teaching should not exceed 35 dB(A).

Sound Insulation: Adequate sound insulation is required between different rooms to prevent noise from disrupting adjacent areas. This is particularly crucial in schools with various noise-generating activities, such as music rooms and sports halls.

Reverberation Time: BB93 sets maximum reverberation times for different types of rooms to ensure clear speech communication. For instance, the reverberation time in a standard classroom should typically be around 0.6 seconds.

Special Considerations: Areas such as corridors, halls, and dining areas must also meet suitable acoustic criteria to minimise noise that could disrupt nearby classrooms.

Design Guidance: BB93 provides specific guidance on the placement of sound-absorbing materials to maintain speech intelligibility and control noise levels. For example, sound-absorbing panels are often recommended for the rear walls and ceilings in classrooms.

These standards comply with various regulations, including Requirement E4 of Part E of the Building Regulations, the School Premises Regulations (2012), and the Independent School Standards (2013) (UK Government Publishing Service) (Gov UK) (Quietstone).
