Aftermarket horns provide a louder, and often more pleasant sound than stock horns. 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 points, i. E. A horn with 118 dB is approximately seven times as loud as a stock horn.
Same thing with listening to loud music. If the notch is already at say on a scale of 1-50, at 45, and you move it to 47, I doubt the increase is that noticeable at that loud of level. 118 to 97 is significant enough to be heard a lot easier, but I seriously doubt that it's 7X greater than a regular horn.
Measuring the multiple factors of something like that probably isn't an accurate measurement to say it's 7X greater. If it was length of something, then obviously that provides a simpler answer, but for noise and sound, I don't think so.

argue all you want.. i just copy and pasted it from when i looked up hella horns.
I'd have to argue this attribute. To me this is the same as bench pressing 97lbs and then to 118lbs. The difference is kinda noticeable, but it surely isn't 7 times as great.

this is commonly known college...she copied and pasted the troof!
...i'll try to find something for ya to read up...
Wikipedia:
When referring to measurements of power or intensity, a ratio can be expressed in decibels by evaluating ten times the base-10 logarithm of the ratio of the measured quantity to the reference level. Thus, if L represents the ratio of a power value P1 to another power value P0, then LdB represents that ratio expressed in decibels and is calculated using the formula:

^ i was thinking about gettin air horns, but they are too big to mount in my car lol. probably gotta mount them under my car or something and have the compressor in my trunk. that just sounds like a lot of work to me.......
i was thinking of crazy ideas and kinda want to fab a set for the rear facing behind me, so i can honk at ppl who tail gate or have their hi beams on.
