Question 1

Do acoustic enclosures satisfy the Control of Noise at Work Regulations 2005?

Accepted Answer

The Control of Noise at Work Regulations 2005 require employers to take all reasonably practicable steps to reduce noise at source before using hearing protection. Acoustic enclosures are an engineering control — the top of the hierarchy of controls — and directly satisfy this requirement. PPE alone does not fully comply where engineering solutions are reasonably practicable.

Question 2

Do OTTOKIND acoustic systems require planning permission or construction work?

Accepted Answer

No. OTTOKIND acoustic systems are modular and freestanding. They install around existing equipment without building work or planning permission, and can be reconfigured or relocated as your production layout changes.

Question 3

What noise reduction level can I expect from an acoustic enclosure?

Accepted Answer

OTTOKIND closed acoustic cabins can achieve up to a 15 dB reduction in ambient noise level — a 97% reduction in noise energy — as demonstrated in the Olsberg case study. The exact reduction depends on source level, enclosure configuration and room acoustics.

Question 4

What is the difference between acoustic screens and acoustic enclosures?

Accepted Answer

Acoustic screens reduce noise spread between areas and suit nuisance noise or partial attenuation. Acoustic enclosures surround the noise source entirely, achieving significantly greater reduction, and are appropriate where noise levels exceed 85 dB and a formal engineering control is required under the Regulations.
