Flared horn
WebThe 30° flare horn has a range from 10.5- to 18.4-dB gain. The gain ranges from 10.5 dB to 14.5 dB for θ = 45° and 10.3 dB to 12.4 dB for θ = 60° for realizable designs. The … WebThe French horn is an intricately coiled metal tube with a large flared bell at one end and a mouthpiece at the other. The basic tubing of the modern French horn is 12–13ft (3.7–4m) long, though there is extra tubing for the valves. The horn player blows into the mouthpiece while buzzing the lips together to sound a note.
