Hospital Ward Acoustic Design in United Kingdom — HTM 08-01 Requirements
Patient wards, recovery rooms, consultation rooms. Typical volume: 100-500 m³.
What HTM 08-01 Requires for a Hospital Ward in United Kingdom
Regulation: HTM 08-01:2013 — mandatory for NHS England new builds
RT60 target: ≤ 0.8s
Background noise limit: ≤ 40 dBA
Local note: NHS England Capital Investment Manual requires HTM 08-01 compliance for all new healthcare construction and major refurbishments.
How to Calculate HTM 08-01 Compliance for a Hospital Ward in United Kingdom
- 1
Identify the applicable United Kingdom standard and target
Look up HTM 08-01 for hospital ward spaces in United Kingdom. The RT60 target is ≤ 0.8s. HTM 08-01:2013 — mandatory for NHS England new builds.
- 2
Measure or model the room geometry
Record the length, width, and height of the room to calculate the volume. A typical hospital ward has a volume of 100-500 m³.
- 3
List all surfaces and their absorption coefficients
For each surface (floor, ceiling, walls, windows, doors), find the absorption coefficient at each octave band frequency (125 Hz to 4 kHz) from ISO 354 test data or a materials database.
- 4
Calculate total absorption and apply the Sabine or Eyring equation
Sum all surface absorption values: A = sum of (alpha x area). Then apply T60 = 0.161 x V / A (Sabine) or T60 = -0.161 x V / (S x ln(1 - alpha_avg)) (Eyring). Use Eyring when average alpha exceeds 0.20.
- 5
Compare result against HTM 08-01 and specify treatment
If the calculated RT60 exceeds the target of ≤ 0.8s, specify additional absorption. Typical treatment cost in United Kingdom is £24,000–£38,000 per 100m².
