How does the ear perceive a low frequency note when the wavelength
is so large and you are standing next to the subwoofer?I've heard so many debates, ie, some say you can't hear a
20hz - 50hz note inside the car but your neighbors can
hear the bass due to the large wavelength.Other person will say that good headphones can produce 20hz - 50hz
notes and you can hear it.Some also say that in order to hear those low frequencies in a movie
theater, one should sit in back.When we hear low frequencies up close, do we really hear the
actual frequency in question coming from the woofer or
do we hear the actually frequency after the wave has completed
the cycle in which case it has bounced around the room for a bit ?My personal experience is this. If I hear a car playing low bass
notes from a distance, I don't hear those same low notes if I sit
inside the car, but you do feel the pressure. Are you just
feeling the pressure, but not hearing the actual low frequencies ?In movie theaters I also hear much lower bass if I sit
in the back vs. sitting in front in which case I hear mostly
tweeters. Same theater I go to and they have the subs up front.When I put headphones on and listen to a 40hz-50hz tone, I do
hear something like fluttering. Am I really hearing the true 40hz
tone or am I hearing something else ?
