Why do lower frequency sound waves travel through walls and floors more easily?

Question

Apartment dwellers will testify that bass
notes are more distinctly heard from music
played in nearby apartments.
Why do lower-frequency sounds get
through walls, floors, and ceilings more eas-
ily?
1. The natural frequency of large walls,
floors, and ceilings is lower than the natu-
ral frequency of smaller surfaces; bass notes
more easily set them into forced vibrations
and resonance.
2. The higher-frequency waves are more
likely to diffract than the lower-frequency
waves.
3. Our ears are more sensitive to the low-
frequency waves.
4. The walls, floors, and ceilings are made of
materials that allow low-frequency waves to
pass.

Answer 1

The natural frequency of large walls, floors, and ceilings is lower than the natural frequency of smaller surfaces; bass notes more easily set them into forced vibrations and resonance.

Answer 2

lower frequency sounds pass through walls because they have a much bigger wave length. The particles in the wall are smaller than the low frequency wave lengths so they are able to pass, but the higher frequency wavelength are smaller than the particles so they blocked. this is why you can put bass speakers anywhere in a room and it sounds fine, but the other speakers have to be places every where, to make sure they dont' get blocked.

Answer 3

hi John.in my view the subwoofer would desire to be interior the middle of the room to lessen status waves as a results of the low frequencies being longer than any room measurement. putting it in a nook will emphasis the better bass notes to unbalance the final sound.in the journey that your ordinary stereo audio equipment can produce forty HZ.you do no longer prefer a sub. there is not any longer lots musical content fabric bellow forty HZ different than the low pedal notes of a pipe organ..Your ordinary audio equipment will provide an superior sound while you're listening to hint.
