I couldn't hear the sound well
I hear a noise offensive to the ear
"I can't think with that noise", she said as she stared at the typewriter
The noise disturbed my sleep
The speed of light is much greater than that of sound
The teacher, not having heard the bell, didn't stop talking
Hearing a strange noise, he jumped out of bed
That's right, that strange sound was the final death scream of the cooling fan
Sound absorbing material is called acoustic material
