The Royal National Institute for Deaf People (RNID), a London-based charity for deaf and hard-of-hearing people, recently asked people what sound they would miss the most among 10 sounds listed, if they lost their hearing.
The most common response was the voice of a loved one. Music and laughter also ranked high, while the sounds of a pet or a car engine were the least-frequent responses.
Natalie Imbruglia, a famous Australian singer, was among several celebrities responding to the survey. She chose laughter.
"My favourite sound is laughter…..belly laughter!" she said. "There is nothing like the abandonment of hysterical laughter. It is contagious and healing, and very joyful."
