Sentences with phrase «airborne sound»

The behavior, along with brain recordings, reveal that the spiders are sensitive to airborne sounds from meters (yards) away.

HEAR YE, HEAR YE: On the phone or otherwise, the process of hearing usually begins when airborne sound waves travel through the ear canal and then hit the eardrum, causing it to vibrate.

A new study shows that they are capable of detecting airborne sound despite not having a tympanic middle ear.

Surprisingly, the measurements showed that not only the terrestrial adult salamanders, but also the fully aquatic juvenile salamanders — and even the lungfish, which are completely maladapted to aerial hearing — were able to detect airborne sound despite not having a tympanic middle ear.

This means that adaptation to aerial hearing following the transition from aquatic to terrestrial lifestyles during the Early Carboniferous was presumably a gradual process, and that the early terrestrial vertebrates without tympanic middle ears were not deaf to airborne sound during the first 100 million years on land.

«It has not completely lost this ability to sensitively detect ground vibrations through the jaw but has gained some of the modern mammal ability to hear airborne sounds,» Luo adds.

But how these insects convert airborne sound waves to fluid - borne sound waves was less clear — particularly as researchers had not yet identified a fluid - filled organ that the waves could travel through.

For sensor cells to receive signals, he says, there must be a mechanism for transforming the large, weak airborne sound waves into smaller but more powerful fluid - borne sound waves that the sensor cells can detect — a process called impedance matching.

Then the scientists broadcast various other airborne sounds.

Nerve cells in the brain of a tiny jumping spider can pick up airborne sounds from at least three meters (almost 10 feet) away, reports Ronald Hoy.

The results show that even vertebrates without outer and middle ears are capable of detecting airborne sound.

DE-SURROUND SOUND: Ambient, airborne sound can wreck a phone conversation, whether you're in a helicopter, on a construction site or surrounded by screaming toddlers.

«Spiders have very sensitive structures all over their bodies for detecting vibration, even at low levels, so we're working on the hypothesis that they detect a surface vibration induced by the airborne sound.»
