Disc horns make a relatively hard sound which is radiated mainly forwards. This achieves good penetration of the traffic noise over a great distance. The sound pattern works best as a set with one high tone horn and one low tone horn. The Sharptones produce 114dB @ 415Hz high tone & 350Hz low tone. Stock horns typically have an output of 97 dB. The decibel scale is logarithmic and therefore the sound pressure doubles for every increase of 3.3 points, i.e. a horn with 118 dB produces approximately seven times the sound preasure as a stock horn.
Sharptone horns are particularly suitable for extreme conditions since they have a greater penetration force due to their size and more powerful electrical drive. Quality is extremely important at Hella. Safety products such as horns demand top precision and reliability. Hella products not only comply with the strict legal regulations but also with the much more demanding requirements made by vehicle manufacturers and the aftermarket. It goes without saying that all Hella horns have ECE type approval.
