Buzz, crackle, bang — sound is everywhere!
Acoustics is the science concerned with the production, control, transmission, reception, and effects of sound.
Sound is biologically important because vibrations carry energy and thus information over distance reliably.
In physics, the sound is a vibration that propagates as an acoustic wave, through a transmission medium such as a gas, liquid or solid. In human physiology and psychology, sound is the reception of such waves and their perception by the brain.
To explain the concept of sound, fun activities were conducted for class 8a students to help them discover how sound travels and how our ears pick it up.
The class was
started off by looking at words that imitate the sounds they represent, such as hiss, rustle, growl, and chirp. This helped them to enrich their language by allowing them to capture sound in writing. They were also invited to brainstorm as many sound words as they could think of.
How is sound actually made? To answer their curiosity a simple experiment was conducted to illustrate the concept. Activity with a loosely stretched rubber band between their thumb and forefinger was conducted and they were asked to predict the inference when they pluck it. Each student tried plucking their own rubber bands and recorded the results.
The students were also given an inside view of how we hear with the parts of the Ear using a model. Many other fun activities were done to explain the concept.
The objective was to make children identify and create different sounds in their environment and develop sensory awareness and language skills in an easy manner.
