Question

how does the sound produce by a vibration objects in a medium reach our ear

Answer 1

as the object vibrates the molecules around the object starts vubrating which reaches our ears in linear motion

Answer 2

The vibrating object produces a series of compressions and rarefactions, one after the other in the medium. These pulses travel one behind the other as the sound waves move forward. When this sound wave reaches our ear, it forces the tympanic membrane tovibrate and thus causes the sensation of hearing.
