  • Sound travels slower through air than by water. In fact, the speed of sound via water is 4.3 times faster than by air. However, sound does travel far faster through steel than both air and water.

The bones in our skulls tend to enhance the lower-frequency vibrations, and that's why our voice sounds lower to us than it really is.

    When you speak or sing, you are hearing your voice conducted through your body, and this sound is slightly lower in pitch than the sound carried through the air to a microphone or listener.]]>     2022-02-17 07:34:54 UTC https://padlet.com/lorincziadri2/soundsandnoises/wish/2052617506     https://padlet.com/lorincziadri2/soundsandnoises/wish/2052618857 If you want to hear how your voice really sounds, make a recording of it, or alternatively just cover up your left ear and speak.]]> 2022-02-17 07:35:47 UTC https://padlet.com/lorincziadri2/soundsandnoises/wish/2052618857 Empty vessels make (the) most noise https://padlet.com/lorincziadri2/soundsandnoises/wish/2052619396 2022-02-17 07:36:11 UTC https://padlet.com/lorincziadri2/soundsandnoises/wish/2052619396 Whipping buddies🤪🤓 https://padlet.com/lorincziadri2/soundsandnoises/wish/2052619770
  • In order for a whip to crackle or make the noise it creates, it must travel faster than the speed of sound.

    • As silent as the grave/dead
    • I don’t want to sound like a busybody, but
    • Love the sound of one’s own voice
    • Ring hollow
    • Sound the alarm
    • Sound like a broken record
    • Get the silent treatment
    • The silent majority
    • Safe and sound

    Less than 70dB: not harmful
    More than 85dB for hours can be hazardous

    Examples: 
    -traffic
    -construction sounds
    -household sounds

    Diseases caused by it:
    -Hypertension
    -Hearing loss
    -Sleep disturbancies

    How can we avoid it?
    -wear earplugs 
    -maintain level about 35-40db
    -don’t use headphones at a high volume

             -    means of soundproofing
                    - adding noise barriers
                    - using damping structures
                    - active antinoise sound generators
    5 elements if soundproofing
              - absorption 
              - damping
              - decoupling 
              - distance
    - adding mass
