Noise, vibration & flows

Silentec is an established leader in tests and simulations of noise and gas flow. Our engineers are often called as expert witnesses in litigation in municipal, superior or federal courts as well as at public hearings on the environment or health and safety. Among the techniques used are:

- Measurements of environmental noise
- Measurement of sound insulation of walls / ceilings (STC IIC)
- Reverberation time, absorption and sound echoes of rooms
- Natural frequency modes - acoustic & vibration in rooms, machines and structures
- Hot exhaust gas: Velocity profiles, pressure loss, noise
- Identification of sources by intensitymeter, correlation and coherence
