Peltor™ Bull’s Eye™ Range
Passive Earmuffs
Product Description
The Peltor™ Bull’s Eye™ passive range foldable earmuffs are available in three different colours; military green, black and red. These products are designed to provide moderate to high level of attenuation that meets the needs of sports shooters and hunters.
When correctly selected and worn these products help reduce exposure to hazardous levels of noise and loud sounds.
NOTE: This technical fact sheet applies to Peltor™ Bull’s Eye™ I, however, for information on Bull’s Eye™ II and III please refer to the 3M™ Peltor™ Optime ™ II and III products as they are identical with the exception of colour.
Key Features
•Modern, stylish slim line cup design
•Bevelled cup increases compatibility with hunting/shooting weapons
•Liquid sealing rings for improved comfort (Peltor™ Bull’s Eye™ I and II only)
•Unique low profile headband design helps maintain constant pressure thus providing confidence in protection
•Large space inside cup helps reduce moisture and heat build-up
•Soft wide cushions helps reduce pressure around the ears and improves comfort and wearability
•Easy to replace cushions and inserts helps keep them hygienically clean
•Easy to understand attenuation symbol to help ensure correct product selection
Applications
The Peltor™ Bull’s Eye™ range earmuffs are ideal for protection against noise arising from many sports shooting and hunting activities.
Examples of typical applications include:
•All kinds of sport shooting, including clay pigeon
•Hunting

Key
APVf (dB) = Mf – sf (dB)
Mf = Mean attenuation value sf = Standard deviation
APVf = Assumed Protection Value
H = High-frequency attenuation value (predicted noise level reduction for noise with L(C) – L(A) = -2dB)
M = Medium-frequency attenuation value (predicted noise level reduction for noise with L(C) – L(A) = +2dB)
L = Low-frequency attenuation value (predicted noise level reduction for noise with L(C) – L(A) = +10dB)
SNR = Single Number Rating (the value that is subtracted from the measured C-weighted sound pressure level, L(C) in order to estimate the effective A-weighted sound pressure level inside the ear).
