Frequently Asked Questions: Hospitals & Healthcare

What are the noise criteria for hospital patient wards?▾
HTM 08-01 recommends a background noise level of NR 30–35 for patient wards, with a maximum night-time level of NR 30 to support sleep recovery. The WHO Environmental Noise Guidelines for Europe suggest LAeq 30 dB at night. Achieving these targets requires careful HVAC design and high-performance sound insulation between wards.
How is speech privacy measured in healthcare settings?▾
Speech privacy in healthcare is measured using the Speech Privacy Index (SPI), where a score of 80 or above indicates confidential privacy as required by HIPAA and NHS guidance. The metric combines sound insulation (STC/Rw), background noise level, and room geometry. Consultation rooms must achieve STC 50+ partitions with sealed perimeters.
What acoustic materials are suitable for infection-control areas?▾
Hospital acoustic materials must be wipeable, non-porous, and resistant to chemical disinfectants. Sealed mineral fibre ceiling tiles (Class 1 fire-rated), perforated metal panels with backing, and vinyl-faced acoustic wall panels are commonly specified. Fabric-wrapped panels are generally not permitted in clinical areas due to infection control requirements.
Why is operating theatre acoustics important?▾
Operating theatres require clear verbal communication between surgical teams while maintaining low background noise to reduce cognitive fatigue. The RT60 target of ≤0.6s combined with NR 35–40 ensures speech intelligibility without excessive reverberation. Laminar flow diffusers must be specified with acoustic attenuation to meet these targets.
