Problem: Outdoor noise penetration into the home.
Cause: Windows left open to provide ventilation. At noisy sites, windows must be closed for acceptable noise reduction.
Solutions: Install suitable ventilation system so that windows can normally be left closed.
- Use a forced air ventilation system as shown in Figure 1, with noise-control features.

- Put the inlet for outdoor air and the exhaust outlet in the quietest locations possible.
- Control noise entering through the inlet and outlet ducts by putting an acoustic duct liner (Figure 2)inside the ducts. Acoustic duct liners have rigid glass fiber lined with a cloth coating and are glued to the inside of the ducts.
