Digital Media Unit 4 – Audio

We looked at what audio is. We learned that sound is a vibration that is picked up by our ears. A loud sound has a lot of intensity. Intensity is measured in decibels. We learned about ultrasound and infrasound and what each of them are. We also learned about the doppler effect which means the pitch of a siren is higher as it approaches you and it is lower as it drives past. We looked at audio in TV and films and saw that theres a lot of different types of sound. After that we looked at audio at home. The audio setups we looked at were mono, stereo and surround sound. At the end we looked at audio equipment like the boom pole, microphone and a headset.
