This massive organ produces sonar pings in, not one, but multiple frequencies.

However, smaller loudspeakers may not produce low frequencies, and so in our example, the 100 Hz component may be missing.

The tube has a fundamental frequency but can be overblown to produce other higher frequencies or notes.

This apparatus was designed to produce several fixed frequencies at different levels of intensity.

He developed one of the first dome tweeters, a drive unit that produces high frequencies.

That is, larger speakers can produce lower frequencies at a higher level than smaller speakers for this reason.

This could produce frequencies higher than 11 kHz.

Mobile phone speakers are capable of producing frequencies above 20kHz.

They also produce similar frequencies, ranging up to 200 000 hertz.

A tweeter is a loudspeaker designed to produce high frequencies, including:
