Noisy Jackhammer Man: Special Headphones Allow Conversation

In summary, the special headphones of "Noisy Jackhammer Man" use noise-cancelling technology to block out loud noise and allow for clearer communication. They can be used in other noisy environments such as construction sites, concerts, and airports. These headphones are highly effective at reducing noise levels, but their effectiveness may vary. Some downsides of using them include bulkiness, discomfort, and higher cost compared to regular headphones. They may not be suitable for everyone, particularly those with medical conditions or sensitivity to noise-cancelling technology. It is important to consult with a doctor before using them.

Noisy Jackhammer man...has special headphones so he can hear you, you cannot hear him

My physics teacher wants us to answer this "A special device can transmit out-of-phase sound from a noisy jackhammer to earphones worn by its operator. Over the noise of the jackhammer, the operator can easily hear your voice while you are unable to hear his, Explain." Now I thought the headphones focused in on a persons voice and canceled the jackhammer...?
