We looked at what audio is and found out that audio is any sound we can hear.Then we looked at loudness & intensity a loud sound has a lot of intensity. Intensity is measured in decibels sound over 120db can cause damage and pain to the ears.pitch and frequency hertz is a unit that measures frequency is how often smoothing happens. The doppler effect that means the pitch of the sound higher as it approaches and the lower as it drives past. The sound in TV and film gives us a lot of information understand what is going on like wild track/voiceover/foley sound . Audio at home mono means sound from only on direction stereo means sound from the left and right .Then we named pieces of audio equipment.
