Muuji qoraalka
Some materials do not allow sound to pass through them easily. They are better at absorbing sound.
Materials that are better at absorbing sound waves are called sound insulators.
Scientists carry out investigations to find out which materials are good sound insulators.
Sound insulators are often soft materials with empty spaces in them, so sound does not pass through them easily.
Scientists and engineers use their knowledge of sound to design rooms and buildings to reduce the volume of sound.
