Technical Terms - Hardware (A-Z) - Headphones

What is the purpose of headphones?

• To convert sound waves into an audio signal

• To limit external sounds

• To generate enough amplitude for far away sound

• To send sound waves a few millimeters to the ear drums

What is the difference between headphones and standalone speakers?

• Headphones need to be audible from far away

• Headphones have smaller and more precise components than speakers

• Headphones have larger components than speakers

• Headphones produce more bass than speakers

What is the purpose of a digital-to-analog converter (DAC) in headphones?

• To connect to a USB port

• To convert digital audio into analog output

• To process analog audio

• To limit the frequency range

Which type of headphones fits snuggly in the ear canal?

• On-ear

• In-ear

• Over-ear

• Earbuds

What is the main feature of noise-cancelling headphones?

• They produce extra bass

• They rest inside the edge of the ear

• They create a quiet listening environment by canceling outside noise

• They have open versions that allow all outside noise

What is the frequency range supported by most headphones?

• 40 Hz to 30,000 Hz

• 20 Hz to 20,000 Hz

• 30 Hz to 25,000 Hz

• 10 Hz to 15,000 Hz

Which headphones help isolate outside sounds?

• On-ear

• Earbuds

• Over-ear

• In-ear

What is the purpose of the microphone in noise-cancelling headphones?

• To detect external sounds and send the opposite waveform to cancel the noise

• To connect to a Lightning port

• To increase the volume of the headphones

• To limit the frequency range of the headphones

Which headphones wrap around the ears?

• Earbuds

• Over-ear

• In-ear

• On-ear

What is the main difference between open and closed versions of headphones?

• Open versions allow all outside noise, while closed versions limit external sounds

• Closed versions produce more bass than open versions

• Closed versions are less precise than open versions

• Open versions have smaller components than closed versions
