Step 1Mechanical energy can be changed into sound energy when an object, such as a drumhead, is vibrated.
The mechanical energy of the vibrating object is transferred into the air, creating areas of high pressure (compressions) and low pressure (rarefactions), which our ears perceive as sound.
Final Answer
Mechanical energy is transformed into sound energy when an object is vibrated, causing pressure fluctuations in the air that our ears detect as sound.
