I am looking to give my kid one of my more sturdier headphones for him to use (we've bought a couple of pairs of those "kids headphones" that aren't as loud as other headphones but they break easy).
What I'm looking for (to further educate myself on using resistors) is a way to figure out the value of resistors I need based on decibels (if possible). For example, if I would like to decrease the levels of a particular set of headphones by -10dB, and knowing the impedance of the headphones (45ohms), what calculation do I need to figure out what value of resistors I would need to decrease the level of the headphones by -10dB (or approximately).
Thanks for any help!
