Noise in the workplace is a serious health and safety consideration.

From power tools and machinery to busy construction or manufacturing environments, constant exposure can cause lasting damage.

That’s why hearing protection is essential. The right PPE doesn’t just reduce noise, it protects workers’ long-term health and keeps your business compliant with safety regulations.

In this guide, we’ll look at the differences between ear plugs and ear defenders, when to use each type, and what to consider when choosing hearing protection for your team.

WHY HEARING PROTECTION MATTERS

Long-term exposure to high noise levels can permanently damage hearing.

Noise level is measured in decibels (dB) using a noise level meter. The higher the dB, the greater the risk.

According to HSE, around 12,000 UK workers suffer from work-related hearing loss each year.

All employers must manage noise risks, provide protection, and comply with UK HSE regulations.

HSE GUIDELINES FOR WORKPLACE NOISE

When noise levels reach 80 dB, risk assessments are required. These are necessary for employers to identify noise risks and provide essential safety controls.

Here's an overview:

  • 80 dB - Risk assessment required. Identify hazards and implement controls.
  • 85 dB - Hearing protection must be provided. PPE is mandatory.
  • 87 dB average exposure - Workplace is unsafe without hearing protection.

TOP TIP: PPE such as ear defenders can help to prevent hearing loss and issues such as tinnitus.

EAR PLUGS: BENEFITS, USES, AND CONSIDERATIONS

Ear plugs are the most common and compact form of hearing protection.

Made from soft materials, they’re designed to sit comfortably inside the ear canal and reduce noise at the source.

They’re lightweight, easy to carry, and simple to use; just roll, insert, and let them expand for a snug fit. Because they seal the ear directly, they can offer a high level of noise reduction.

Benefits of ear plugs:

  • Easy to combine with other PPE
  • Available in reusable or disposable styles
  • Lightweight and comfortable for long wear
  • Small and discreet, they're ideal for use on the go

Points to consider:

  • Poor fit can reduce protection
  • Can cause a ‘blocked’ feeling for some wearers
  • Hygiene is key! Always handle with clean hands

Ear plugs are a great choice for workplaces such as:

Earplug dispensers and banded earplugs

EARMUFFS: BENEFITS, USES, AND CONSIDERATIONS

Earmuffs (or ear defenders) sit over the ears to block and absorb sound.

They’re quick to fit, adjustable, and ideal for consistent, high-level noise protection.

Each model is rated with an SNR (Single Number Rating) value. The SNR is a measure of how many decibels of sound the equipment can reduce. Earmuffs typically provide an SNR between 25 and 40 dB, depending on the design and seal quality.

Benefits of earmuffs:

  • Can attach easily to safety helmets
  • Adjustable for a secure, comfortable fit
  • Durable and reusable for long-term protection
  • Simple to fit and remove – no direct contact with the ear canal

Points to consider:

  • Can feel warm during long shifts
  • May interfere with eye or face protection
  • Bulkier to store and transport than ear plugs

Earmuffs are ideal for workplaces such as:

Ear defenders for hearing PPE

EAR PLUGS VS. EARMUFFS: WHAT'S BEST?

The choice depends on noise levels, work type, and PPE compatibility.

FEATURE

EAR PLUGS

EAR DEFENDERS

NOISE REDUCTION (SNR)

35-40 dB

25-40dB

EASE OF USE
Small and quick to insert

Simple to fit and adjust

HYGIENE Need regular cleaning; can pose hygiene risks

Easier to keep clean; cushions absorb moisture

COMFORT Lightweight, but can feel blocked

Heavier, but well-padded and adjustable

COMPATIBILITY Easy to use with other PPE

Can interfere with face or eye protection

TOP TIP: In very loud environments, using both ear plugs and earmuffs provides maximum protection.

MAINTENANCE AND REPLACEMENT GUIDE

Always ensure that you're checking your team's hearing protection:

  • Replace ear cushions periodically.
  • Keep all hearing PPE in clean, dry storage.
  • Check ear plugs for wear, tears, or hygiene issues.
  • Follow manufacturer guidance for the maximum reusable period.
  • Inspect ear defenders for cracks, damaged cushions, or loose headbands.

Proper maintenance ensures consistent dB reduction and compliance with HSE regulations.

FAQS

Should I use earmuffs or ear plugs?

Choosing between earmuffs and ear plugs will depend on:

  • Required dB reduction
  • How much PPE is needed
  • Cleanliness and hygiene risks

High noise environments may require both ear defenders and ear plugs to be worn.

When is hearing protection needed?

Hearing protection is required in the workplace when noise levels reach 85 dB. This is an unsafe exposure level, and PPE should be provided. 

How to find the best hearing protection for work?

The best hearing protection for the workplace will depend on both practical and comfort factors. 

Consider factors like these to make the right choice:

Can you wear earmuffs and ear plugs in the workplace?

Of course! They’re both common types of hearing protection PPE. They must be provided for free in high-level noise environments of 80+ dB. 

If you’d like to wear ear protectors or noise cancelling headphones at levels lower than this, check with your employer.
