Hospital Ward Acoustic Design in Canada — WELL v2 Feature 74 Requirements
Patient wards, recovery rooms, consultation rooms. Typical volume: 100-500 m³.
What WELL v2 Feature 74 Requires for a Hospital Ward in Canada
Regulation: WELL v2 for Healthcare
RT60 target: ≤ 0.6s
Background noise limit: ≤ 35 dBA
STI requirement: ≥ 0.60
Local note: Canadian healthcare facilities use CSA Z317.13 for infection control — acoustic design must integrate.
How to Calculate WELL v2 Feature 74 Compliance for a Hospital Ward in Canada
- 1
Identify the applicable Canada standard and target
Look up WELL v2 Feature 74 for hospital ward spaces in Canada. The RT60 target is ≤ 0.6s. WELL v2 for Healthcare.
- 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 WELL v2 Feature 74 and specify treatment
If the calculated RT60 exceeds the target of ≤ 0.6s, specify additional absorption. Typical treatment cost in Canada is C$30,000–C$48,000 per 100m².
