Why do some countries encourage the use of suppressors?

Think about it.

The threshold for potential instant noise-induced hearing loss is 120 dB SPL at the ear. A rifle can exceed 170 dB SPL at a distance of one meter[1]. When you're shooting a rifle, it's going to be cradled firmly against the shoulder -- a lot closer than 1 meter. Even the lowly .22lr fired from a handgun can exceed 160 dB SPL[2]. A suppressor can knock that down about 30 dB. 130 dB is still a lot, but it's out of the 'will-immedately-and-permanently-damage-your-hearing' range at least, and makes further hearing protection (earmuffs, earplugs) that much more effective.

tl;dr - A suppressor is safety equipment.

Maybe it should be a thing for the gun range then. Require people to attach them there and require that they leave them there.

In general, if people are shooting outside in my neighborhood, I'd rather be woken up. That's not the type of thing that should go unnoticed. And I live in the middle of San Franciso where I've watched people get shot and killed.

Honestly, if suppressors were widely available to the general public, I'd love it for people to be using them on the range. Even if he's on the far opposite lane of the range, the guy shooting a .300 Winchester Magnum is still damn loud. But I don't think they should be limited to the gun range.

Out in the suburbs, or further out on the edge of the city where things start to get rural, if someone has a big enough backyard that they can safely fire a .22, I'd rather they use a suppressor. It's not a case of not being woken or not by the danger of violence in the neighborhood, it's a case of neighborly manners. It's more similar to me not running a guitar amplifier after 9pm. Nobody likes to be disrupted by loud noises when they don't need to be.

As someone living in a rural area, near a nature preserve, I'd prefer the opposite.

I'm tired of being woken up way too early in the morning by gunshots. Waterfowl season started last weekend, so it was shotguns going off a mile away. Rifle season for deer starts soon (it's bowhunting season now), and that will bring its own set of loud noises from even closer.

I'm all for suppressors, if only so I can sleep past 5AM without having to keep my windows closed.

It's a safety issue. Suppressors do not work like the purely fictional "silencers" of the movies. They take a deafening, hearing-injury-inducing bang and turn it merely into a loud noise. Modern suppressors actually aid accuracy too, making collateral damage less likely.

Maybe so that, unlike in the U. S., if one lives within five miles of a gun range, one won’t be awakened on Sunday morning by gunfire. Me, I don’t mind it all that much, but there’s a gun range I can hear from the house. I haven’t mapped it, but it is at least three miles away. Here’s the kicker: I live smack in the middle of Redmond, WA. You know, where Microsoft is at? In case you were thinking I live in the sticks. But the gun range was here long before Microsoft showed up. (That one up by Willows Road in the middle of a subdivision, if you’re local.)

Haha! Those were gun shots? TIL!

I can't speak for those countries, but I wish my state would encourage or even require them as a matter of politeness, quality of life and public health. Suppressed guns are less of a noise nuisance to neighbors/other land users, disturb wildlife to a lesser degree, and are much safer for hearing. In the case of small calibers they can eliminate the need for separate hearing protection which increases situational awareness and thus safety. They also increase accuracy of course (longer barrel).

They are expensive, but not prohibitively so imo. It's unfortunate the movie/TV industry really seems to have poisoned the well a bit there.

Neighborliness and hearing protection are the reasons I've heard.
