In the meantime, check out this article on silencers Colonel Smoothbore wrote from 2017:
In past columns I’ve discussed suppressors or as they are often referred to, silencers. These simple devices can and do reduce hearing loss that results from exposure to the extremely loud and concentrated noise that results from gunfire. Two bills have been introduced in Congress that would change the procurement process for individuals that wish to obtain a silencer. The Hearing Protection Act of 2017 was introduced in the Senate by Senator Mike Crapo (R-ID) with co-sponsors Sens. Jerry Moran (R-KS) and Rand Paul (R-KY) as S.59. Representatives Jeff Duncan (R-SC) and John Carter (R-TX) – together with 42 co-sponsors – introduced a similar bill in the House as H.R. 367.
Rather than having to fill out an application, pay $200.00 for a NFA tax stamp, and wait for ATF approval that can take from 3 months or more, all one would have to do is fill out ATF Form 4473, pass the requisite NICS background check, then pay for and take delivery of one’s chosen suppressor device.
In typical fashion gun control advocates are spreading the usual “fake news” regarding the use of silencers. They would have us believe the Hollywood version that silencers make gunfire blasts from a firearm turn into a whisper; that simply isn’t true. Suppressors are capable of reducing the noise from a gun by about 30 decibels. Here are a couple of examples; the peak sound pressure of a gunshot ranges from a low of 144 decibels (.22 caliber rifle) to 172 decibels (.357 caliber revolver). Suppressed sound levels will be reduced to about 115-140 decibels. These levels are still louder than your average car horn blaring 3 feet away, 
hardly a whisper.
I have personally suffered substantial hearing loss and I have tinnitus in my left ear. The wind blowing noise in my ear never stops, is extremely nettlesome, and, most importantly, there is no cure. I have tried almost all of the “natural” homeopathic remedies, none have worked. While exposure to gunfire isn’t the main cause of hearing problems, it has been a factor. OHSA and NIOSH have both determined that a single noise blast of 140 decibels can cause serious and permanent hearing damage and loss. It only makes sense to ease restrictions on suppressors so that they are more readily available to the shooting public. Another plus is that as the market for silencers increases, their cost will decrease, possibly dramatically; look at what has happened to flat screen HD TVs in the last decade.
Gun control advocates are claiming that crimes involving suppressed firearms will sky-rocket with the easier access to silencers.
