Sound recording

  1. 1. Indoors, empty corridor The lights could affect the number of decibels. The brick walls could affect the reflection of the sound meaning there will be an echo.In this hallway, in the recording it seems to have an echo and sound louder, this seems to bebecause of the walls, refraction is what makes it seem louder, the walls and floor seeming to haveproperties that make the refraction possible. Furthermore with the echoing this means either thefloor or walls are reflecting the sound waves. Heat also factors into meaning the decibel (loudness)so the heat from the lights could have possibly affected how loud it sounded.
  2. 2. Outside The canopy affected the sound in different ways. The cold air changed the number of decibels of the recording.We did the recording under the canopy to the left of the screen. There is a slight echo from beingunderneath the canopy as the metal and plastics could have reflected the sound. Furthermore Ithink that this caused the refraction of the sound and also there was a raise in decibels because ofthe cold air.
  3. 3. ElevatorIn this one what happened was because of the glass it helped to add a refraction and because of theenclosed space the decibels were a lot higher.
  4. 4. CanteenWith this there was a lot of background noise because of the place where we did the recording sopeople can be heard in the background. There was no refraction or echo and the decibels were thesame, although it may have seemed quieter because of other loud noises such as people talking.
