Course Learning Outcomes:

1. Calculate the basic parameters that define acoustic noise such as the speed of sound in different media sound pressure sound pressure level acoustic impedance sound power sound power level sound intensity sound intensity level and loudness.
2. Calculate the various noise criteria associated with rooms and human hearing such as noise rating criteria and equivalent noise weightings over a range of frequencies or over a given time period.
3. Demonstrate an understanding of different acoustic noise measurement instruments and analysis equipment such as microphones sound level meters sound intensity probes dosimeters and spectrum analyzers.
4. Calculate sound radiation and propagation parameters such as sound radiation through air sound reflection coefficients sound transmission through and around objects sound transmission loss insertion loss outdoor sound sources meteorological effects room acoustics near field effects and reverberation effects.
5. Calculate the acoustic noise that is likely to be generated by typical industrial machinery such as fan noise electric motor noise pump noise compressor noise gear noise valve noise HVAC noise traffic noise and train noise.
6. Calculate the effects of various noise control techniques such as sound absorbing materials sound absorbers noise partitions noise enclosures sound barriers in rooms and outdoors silencers vibration isolation and active noise control.
7. Calculate design the optimum dimensions of different surface treatments with given or estimated material properties for a room of known dimensions that is experiencing a given or measured level of acoustic noise.
8. Design including specifying materials material properties optimum dimensions fabrication methods joining and cutting tolerances and cost estimates an acoustic noise reduction enclosure given the specifics of a noise source including noise levels in different octave bands and the room size and other contents.
