HSE – Top 10 Noise Control Techniques
This HSE guidance provides ten practical noise control techniques that can be applied across a wide range of industries to reduce workplace noise exposure and minimise the risk of Noise-Induced Hearing Loss (NIHL).
The guidance focuses on simple engineering and management controls that can often achieve substantial noise reductions quickly and cost-effectively. Rather than relying solely on hearing protection, the document promotes the principle of controlling noise at source wherever reasonably practicable.
The techniques are applicable to manufacturing, engineering, construction, woodworking, food production, process industries and many other workplaces where employees may be exposed to harmful noise levels.
Topics covered include:
• Reducing noise at source
• Preventing vibration and structure-borne noise
• Controlling impact noise
• Managing compressed air noise
• Acoustic enclosures and barriers
• Equipment maintenance
• Workplace layout and segregation
• Selection of quieter machinery
• Employee involvement and training
• Ongoing noise management
This resource provides a useful starting point for organisations seeking practical solutions to workplace noise problems and supports compliance with the Control of Noise at Work Regulations 2005.

Noise is often viewed as a hearing protection issue when, in reality, effective noise management follows the same hierarchy of control principles applied to airborne contaminants, dusts and fumes.
For LEV engineers and occupational hygienists, many of the causes of excessive workplace noise are familiar. Turbulent airflow, poorly designed ductwork, excessive fan velocities, vibration transmission and inadequate maintenance can all contribute significantly to workplace noise levels.
The HSE’s Top 10 Noise Control Techniques reinforces a key occupational hygiene principle: control hazards at source wherever reasonably practicable. Engineering controls typically provide a more reliable and sustainable solution than relying solely on personal protective equipment.
The guidance is particularly relevant when evaluating existing LEV systems. Excessive system noise may indicate poor airflow design, high-pressure losses, unsuitable fan selection or deteriorating components. In many cases, improvements that reduce noise can also improve system efficiency and energy performance.
Employers should remember that hearing loss is permanent and irreversible. Effective noise control requires a combination of good equipment selection, preventative maintenance, workplace design and employee engagement. Hearing protection should be regarded as the final line of defence rather than the primary control measure.
For LEV professionals, understanding noise generation mechanisms can support better system design, improved commissioning outcomes and enhanced worker protection.
