Acoustics



Acoustics is the study of sound waves and how they are soaked up or reflected. A room or hall that is said to have good acoustics, means that the sound being produced in them can be clearly heard by the people that are listening to the sounds being produced. Concert halls usually have good acoustics. Architects usually consult an acoustic engineer when designing the inside of a concert hall or theatre.

Project


Find practical examples to prove some principles of acoustics.

Eg: 1. Visit a concert hall  2. Try some experiments in the classroom, remove all the desks and chairs, hang soft wall hangings or empty the walls of soft hangings to reveal the difference in sound. Individual students could go in the room to make sounds and hear the difference between the conditions of the room and write their findings.  3. Out door amphitheatres can also be a lot of fun, if there is one close by.  4. Make a simple string telephone with two tin cans this example shows the ability of sound waves to travel through solid material. Remember to test the different conditions e.g. with a tight string and a slack string or something touching against the string.

Write down your findings.
