No, it's not. If you shoot that without hearing protection, you will permanently damage your hearing fairly quickly. It might take a while for that damage to become noticable, but that doesn't mean it isn't happening. Your Octane 45 is about 130 dB at best; that's louder than a jackhammer and loud enough to easily damage your hearing.

No silencer is medically hearing safe. Repeated exposure to noises as low as 85 dB can cause hearing damage. Here's a good link from the American Hearing Research Foundation:

"Habitual exposure to noise above 85 dB will cause a gradual hearing loss in a significant number of individuals, and louder noises will accelerate this damage. [...] The highest permissible noise exposure for the unprotected ear is 115 dB for 15 minutes per day."

In contrast, the quietest .22 silencers on the market rarely get a shot down below 115 dB. Most pistol silencers are between 125 and 130 dB. Most rifle silencers are between 133 and 138 dB.

Silencers definitely make a huge difference, that's why I own three of them and I plan to buy more. But claiming they're "hearing safe" is incorrect and irresponsible. The industry bases their claims of a silencer being "hearing safe" on a misinterpretation of OSHA rules, and that claim is disingenuous at best.
