3M PELTOR Optime III Noise Cancelling Ear Muffs with Headband
The double casing of the 3M PELTOR Optime III Noise Cancelling Ear Muffs with Headband minimises resonance, which maximises attenuation of high frequency sounds. The ear muffs protect against noise levels up to 35dB and are ideal for use in engine rooms, power stations and airports.
Key Information
- EN 352 - 1
- SNR (Simplified Noise Reduction): 35dB
- One universal size
- Price is per pair of ear muffs
What Are the Key Features of the Noise Cancelling Ear Muffs?
- Protection: Shields your ears in loud environments up to 35dB
- Reduces Resonance: Unique double casing technology minimises the resonance effect
- Comfortable: Soft, wide foam cushions help to reduce pressure around your ears
- Wearable: Large space within the cups to prevent a build-up of moisture and heat
- Hygienic:Easy to replace cushions and inserts keeps the ear muffs clean
- Secure: Headband for comfortable and secure fit
What Are the Safety Specifications of the 3M PELTOR Optime III Noise Cancelling Ear Muffs?
The 3M PELTOR Optime III Noise Cancelling Ear Muffs have been tested in accordance with a number of specifications to ensure your safety. The standards that the ear muffs meet include:
EN 352 - 1
The Ear Muffs meet EN 352 - 1 for ear protection. This means that they are suitable as ear defenders in loud conditions.
SNR (Simplified Noise Reduction)
The Ear Defenders achieve an SNR score of 35dB. Further attenuation ratings are as follows:
- High frequency = 40dB
- Medium frequency = 32dB
- Low frequency = 23dB
What Are the Uses of the 3M PELTOR Optime III Noise Cancelling Ear Muffs?
The noise cancelling ear muffs are ideal for use in extremely loud environments. Following are some suitable applications:
- Airports
- Power stations
- Marine engine rooms
- Print works
How Comfortable Are the 3M PELTOR Noise Cancelling Ear Muffs?
The large soft cushions of the ear muffs will reduce pressure on the ears and head. The inside of the cups are large, which helps to minimise an uncomfortable build-up of moisture and heat.
Double-Casing of the Noise Cancelling Ear Muffs
The double-casing of the ear muffs minimises resonance in the holder casing. This means allows for maximum attenuation of high-frequency sounds.
What Is Signal to Noise Ratio (SNR) and Noise Attenuation?
The SNR ratio of ear-protection indicates the amount by which background noise will be reduced, or attenuated. So if you work around machinery with a background noise of 100dB, then ear muffs with an SNR of 32 will reduce the background noise to 68dB, protecting your ears. Ear muffs will reduce the overall background noise by differing amounts depending on whether the noise is medium, low or high frequency.
Sizing of the 3M PELTOR Optime Noise Cancelling Ear Muffs
The Ear Muffs are available in one size that should suit most users.
