Question

which of the following statements is true of sound transmission through various mediums? a) sound insulators prevent sound from being transmitted better than elastic solids. b) elastic solids prevent sound

Explanation:

To determine the correct statement, we analyze the properties of sound transmission:

• Sound insulators (like soft materials, air - filled spaces) are designed to reduce sound transmission. Elastic solids (like metals, dense materials) are good conductors of sound because their particles are closely packed, allowing sound waves (which are mechanical waves requiring particle interaction) to travel quickly. So sound insulators prevent sound transmission better than elastic solids.
• Option A states "Sound insulators prevent sound from being transmitted better than elastic solids" which matches the above analysis. Since the option for B is cut off, but from the given part, A is a correct statement about sound transmission through mediums.

Answer:

A) Sound insulators prevent sound from being transmitted better than elastic solids.
