Industrial fans are usually required for kitchen or dust exraction.

Fans can cause noise problems internally within the duct system before breaking-out through the exhuast or through the fan case break-out to atmosphere.

Sound Planning considers all elements of potential break-out noise; calculating noie levels at the nearest noise sensitive receivers in accordance with British Standard 4142.

Appropriate noise mitigation measures are introduced to reduce noise levels down to satisfactory levels in accordance with the Local Authroity Guidelines and national standards.

Noise Mitigation:

• Fan Jackets
• Duct Attenuators
• Acoustic Louvres
• Enclosures
