Sound waves can bend around obstacles such as corners and travel through the air. This allows the sound of a man's voice to reach your ears even if he is not in your line of sight. Sound waves reflect and diffract, enabling you to hear the sound even when the source is not visible.

A special device can transmit sound that is out of phase with the sound of a noisy jackhammer to the operator by means of earphones Over the noise the operator can hear your voice but you cant hear?

This device likely uses noise-canceling technology to generate sound waves that are out of phase with the jackhammer noise, effectively canceling it out. The operator can then hear your voice minus the noise, making communication clearer. However, since you don't have the earphones that are playing the out-of-phase sound, you cannot hear the canceled noise.


Is it true or false If you are in an environment where you cant hear what a co-worker is saying without them significantly raising their voice then ear protection should be used?

False. If you are in an environment where you can't hear your coworker without them significantly raising their voice, it is not necessary to use ear protection. Ear protection is typically used in environments with loud noises that can cause hearing damage over time. If the issue is simply with hearing your coworker, then other solutions such as moving closer or finding a quieter location to communicate can be explored.

Why can't we imagine of a world without sound?

Sound is a fundamental aspect of our perception and communication. Imagining a world without sound would be challenging because it plays a crucial role in how we experience the environment around us. Additionally, sound is deeply integrated into our everyday lives, making it difficult to conceive of a reality completely devoid of it.
