5. Can i shoot without hearing protection with a Stalon silencer?
Hearing protection or not, is really a matter of experience, flexibility and of course sound level.
The important thing is that you use some form of sound-reducing equipment (read: silencer or hearingprotection)
We have gathered information and comparisons so that you can make as good decision as possible, the choice to shoot without hearing protection or not, is entirely up to you.
Rifle in caliber .308 with a barrel length of 51cm: ~ 167.9 dB (C)
Rifle in caliber .22LR with a barrel length of 56cm: ~ 143.2 dB (C)
Stalon W110 in caliber .308: ~ 132.9 dB (C) from shooters left ear.
Stalon VICTOR in caliber .308: ~ 133.3 dB (C) from shooters left ear.
Hearing protection for hunting in .308: ~ 139.9 dB (C)
Firm hand clabbing, 1 m from the instrument: ~ 123.7 dB (C)
It is very difficult to determine with the above comparisons how high or how low the sound levels are, it have to be experienced.
The EU (European Union) has established a directive for a safe "working environment" in noisy environments. When develop our products we always take these levels (137 dB (C)) into account to.
“... minimum requirements for the protection of workers from risks to their health and safety arising or likely to arise from exposure to noise ... Three distinct levels are defined for continuous and impulse noise:
1) The lower exposure action values: continuous noise: LEX,8h = 80 dB(A) impulse noise: ppea k= 112 Pa (Lpeak = 135 dB(C)). The employer has to make available individual hearing protectors to the employees.
2) The upper exposure action values: continuous noise: LEX,8h = 85 dB(A) impulse noise: ppeak = 140 Pa (Lpeak = 137 dB(C)). The individual hearing protectors have to be used
3) The exposure limit values: continuous noise: LEX,8h = 87 dB(A) impulse noise: peak = 200 Pa (Lpeak = 140 dB(C)). This exposure level shall not be exceeded. For the determination of the effective exposure, the attenuation provided by the protection devices is taken into account."
