"The thing about low-frequency sound is that it can go for miles," he said.

I kept getting a series of low-frequency waves that were like nothing I'd ever seen before.

They turned down my request to follow up research on those low-frequency waves.

However, they are reported to have limited low-frequency reproduction abilities.

The elephants were the first land mammals known to use low-frequency sounds.

For the record, though, low-frequency whale calls can and do travel thousands of miles under the sea.

There are just some differences in very low-frequency lexical items.

We're still getting some low-frequency stuff, and the ice has been cracking apart ever since the explosion.

The signal for it to emerge seems to be the low-frequency noise of rain.

Some people find low-frequency noise and its vibrations very unpleasant.

The middle ear seems to be adapted for the reception of low-frequency sounds.

"The idea is that these low-frequency sounds were important in religious rituals for changing states of consciousness," he said.

It takes the low-frequency load off the other speakers, allowing them to be smaller and sound better.

Some birds also use low-frequency sound signals for territorial, sexual and other social communications.

At the extreme end of the scale, there are those who believe that these low-frequency electric fields cause cancer.

"On the other hand, low-frequency violin notes tend to go straight out.

A regular hearing aid picks up every sound, including low-frequency background noises.

Those targets had been identified last week by special low-frequency sonar equipment.

Low-frequency bass sounds resonate from its lungs and body wall.

She heard the low-frequency beat pulsing faintly through her walls.

No, it did not seem to vibrate when low-frequency sound waves were applied.

It is attracted to low-frequency sounds, which are indicative of struggling fish.

The low-frequency call may carry over a mile, drawing females in from the surrounding area.

The use of a low-frequency cave radio can also verify survey accuracy.

The double negative parameters are a result of low-frequency resonances.

Thinking about my history, I heard this on a low frequency.

These low frequency systems are still used a lot today.

There was another sound too, of such low frequency as almost to be felt rather than heard.

Light of low frequency could carry more energy only for the same reason.

The light from a star moving away is seen at a lower frequency, or more red.

Lower frequencies in the bass range are difficult to form.

Lower frequencies than can be heard are detected this way.

Each user group would use a different low frequency tone.

This sound is special due to the extremely low frequencies of it.

The ear cannot hear the low frequencies of the dynamic system.

The longer the array, the lower frequency the pattern will control.

Lower frequencies do not have enough bandwidth available for television.

The system used low frequencies from 70 to 129 kHz.

In particular for low frequencies this antenna form is interesting.

These are materials where the relaxation rate is at much lower frequencies.

This is a desirable feature especially when using low frequency data.

Other studies have found the theme, but with lower frequency and popularity.

For most audio applications more power is needed at low frequencies.

The lower frequencies at high power densities present a significant risk.

At about the one minute mark, a single, low frequency pulse appeared.

The lowest frequency a human eye responds to is red.

"Give ourselves one of the lower frequencies to use, to contact the Council."

The roof began to tremble at a very low frequency.

However, the power that an animal can couple into the ground at low frequencies is related directly to its mass.

It is most noticeable in the low frequency radio waves.
