Likely not to an appreciable degree. Horns make a sound louder by giving the thing producing the sound more air to push against, so the pressure waves actually build up and travel through the air instead of just pushing it around.
Meanwhile a gunshot is loud because it’s already a massive pressure wave. Silencers work by containing the pressure spike and allowing the gas to expand and cool.
In fact, muzzle cones were added to rifles and machine guns during the early 20th century for a similar reason, to suppress the muzzle flash from the unburnt powder hitting fresh air and combusting by giving the gases a place to expand and cool. They did also tend to direct some of the concussion away from the shooter, but it’s debatable how effective this was.
