I'm not trying to be rude, and I actually appreciate your thoughtfulness of wanting to not be "that guy", it's just that the facts are stacked against you here because you said "50 BMG".
At 172 decibels the 50 BMG is twice as loud as a 20" 308, and almost four times as loud as an 24" 6XC. Then you put a a brake on it and redirect the blast towards the shooters next to you. The volume they're blasted with can double, or even double then half again, compared to a bare muzzle. Even with double ear pro it's not safe to be within 10 feet of the brake on a 50. It's barely safe to be the shooter, they're largely protected by the angles of the baffles but even then it's questionable to not wear double ear pro. And that's not a WAG, that's math.
3M Peltor X5 muffs have an NRR of 31 dB, which is the highest certified rating I'm aware of. Combined with plugs, that gets you a max of 36dB NRR. The OSHA impulse threshold of 140dB, plus the protection of double ear pro, means you can be exposed to 176 dB without suffering hearing damage. At ~5ft the pressure level of your braked 50BMG will be at least 182 dB if using an effective brake that redirects any blast past 90* behind the bore, and could be as high as 187 dB. At any closer than 10 feet it's impossible to mitigate the sound pressure below the damaging level of 176 dB with any hearing protection devices. At 15 feet it's still louder than being 5 feet from a normal 30 cal centerfire rifle. This means that any sound redirected at adjacent benches cannot safely be mitigated other than by distance. Which means that smart people should refuse to sit on at least the two benches on either side of you.
I stand by saying that it's impossible for a brake (specifically, other things can, but not a brake) to functionally reduce recoil and not clear the benches beside you because the brake has to be angled somewhere between 0-60 degrees on the shooter side of perpendicular to the bore in order to reduce recoil. That means it's literally pointing at the shooters next to you. The only way to mitigate the sound pressure of your shot is with distance, there is no hearing protection available that is sufficient to be within 10 feet of your muzzle. It's physics, the ejecta mass of the propellent is a component of recoil, that's what the brake is redirecting to reduce both the overall momentum of the rifle and peak force of recoil, and that's what creates that sound pressure waves.
There's also the fact that no one should sit within 10 feet of you anyways because the danger of fragmentation on a baffle strike, but that's all brakes, and no one ever seems pays attention to that little factoid anyways. This is part of why I detest public ranges, but I digress...
The suppressor/brake combination is the best way to achieve the goal you stated. This IS the suppressor forum after all. And that combination will work, because the expansion chamber of the suppressor will reduce recoil - they are specifically highly effective at reducing peak force because of how they slow the ejecta mass leaving the muzzle. They're not as effective as brakes in overall momentum reduction because they don't redirect any of it rearward, but they spread the force out over a much longer time frame. A brake on a suppressor isn't as effective as a bare brake in reducing overall momentum because a significant amount of the ejecta velocity is lost inside the suppressor, but it's still move effective than a bare suppressor. Suppressor/ brakes is a good combination for your usage. I don't use the brake option on my SilencerCo cans, but that's mainly because the brake isn't very effective with it's tight baffle spacing and 90* orientation.
