4.4. Acoustic standards: legislation and guidance

Acoustic standards and guidance have been established to promote good listening conditions and accessible speech for everyone. The standards and guidance provide criteria for school acoustic design and access.听

Building Bulletin 93 ()

The guidance for new build schools and classroom refurbishments in the UK are set out in BB93. Different performance standards are set out for learning spaces in primary and secondary schools and school-site maintained nursery settings, and enhanced acoustic criteria for deaf pupils and pupils with specific hearing and communication needs are also included.

BB93 states that school senior leaders 鈥溾€�should anticipate the needs of deaf and other disabled children as current and future users of the school鈥�.

Acoustics of schools: a design guide听

Chapter 6: Acoustic design and equipment for pupils with ‘special hearing requirement; states that:

“Favourable acoustic conditions will benefit large numbers of pupils within mainstream schools who have special hearing requirements. These pupils include pupils:

with permanent hearing impairment
with speech, language and communication difficulties
whose first language is not English
with visual impairments
with fluctuating hearing impairments caused by conductive hearing loss
with attention deficit hyperactivity disorders (ADHD)
with an auditory processing disorder or difficulty

Together, the number of pupils falling into one or more of these categories could conceivably be a significant proportion of every mainstream classroom. It is therefore important to consider every teaching and learning space as being one where there are pupils who have special hearing requirements.” (p.63)

Considerations for QToDs

Has the acoustic audit of learning spaces been completed?
Has the school considered if and how classroom acoustics could be improved over time to improve access to learning? If acoustics could be improved, has the school included this in their school accessibility plan?
Acoustic standards also apply to temporary buildings (see BB93).
