Horns can be used singly, but are often arranged in pairs to produce an interval consisting of two notes, sounded together; although this doubles the sound volume, the use of two differing frequencies is more perceptible to the human ear than two horns of the same frequency, particularly in an environment with a high ambient noise level. Typical frequencies of a pair of horns of this design are 500Hz and 405–420Hz (approximately B 4 and G ♯ 4, minor third).Small battery-operated electric horns, as well as the traditional single-reed bulb horn, are typically used on bicycles.
