ok, if u have read my last 2 threads, i was looking for a science project. I have found one. The project is to build two guitar pickups, and test if a stronger magnet will make the sound better. But one problem, i do not know how to test them to see which sounds better, because i need to collect data with numbers to do the project. So if u could tell me (or give me a link to somewhere) how i can compare the two pickups PLEASE TELL ME!!! or if you have any other ideas tell me those to, ok thanks

Measure the sound output of both?

See which is louder with different guitar settings,

That's all I can think of.

That's pretty much it, I think. But it will test of "hotness" of the pickups. You can't scientifically prove that one pickup sound better than the other, since it's based on opinion. You can only measure which one puts out a stronger signal.

Measure how much sound they're putting out.

Have the same amp settings all the time. Change between all bass on guitar, all mids, all treble (assuming you have all those), put all of half. Measure how loud the output is (in dB).

use an oscilloscope and measure the output signal? Or use a multimeter to compare output voltages...but you'd need test conditions. Nounting the pickups side by side under a single string, both exactly the same distance from an anchor point, would be fair. After doing that you can listen to them mounted in a guitar and see which one sounds better to you. You can quantify the output because it's measureable, so your hypothesis could be "Does a more powerful pickup sound better?"

well which pickup sounds better is more of an opinion than something that can be measured. Instead of looking for a scientific measurement, maybe take a survey or something otherwise its completely subjective. Even if pickup A sounds better than pickup B to you, another guitar player might take the tone that is less appealing to you and apply it differently to make it sound more appealing based on how they play.

Get a bunch of people to rate the sounds quality from 1-10, then find averages, standard deviations and other statistical things.

thanks i thik ive found what i want, an oscillooscope cost atleast 500 dollars and i dont have that kinda money, but the multimeter is definetly something im going to research about knowing i already have one. thank you so much
