The loudest natural sound on earth is caused by an erupting volcano. The number one cause of hearing loss is exposure to excessively loud sounds (85 decibels or higher). Dogs can detect sounds at a far higher frequency than humans can. They have the ability to hear sounds or noises that ...
Recognizing the sound timbre by humans: A mismatch field magnetoencephalography (MEG) study.A study of various aspects of the human auditory system was performed using measurements of the magnetic field produced by the brain (MEG). The process of the recognition of the sounds of different timbre...
Just like humans, birds rely on sound to communicate, too. Often, birds recognize their mates or young by sound rather than sight. Hungry young birds use begging calls to let their mothers know it is feeding time, and warning calls are other sounds given out frequently by the adults. In ...
Humans can tell the difference between tenths of a bell, so loudness is measured in decibels. Using a sound meter, how much street sound a closed window keeps out of a room can be calculated with algebra.[3] As a sound wave gets a bigger diameter by moving away from the sound source...
The softest sound humans can hear, at the very threshold of hearing, has a loudness of 0 decibels. A moderate conversation has a loudness of about 60 decibels, and thunder at very close range has a loudness of about 140 decibels. Sound with intensity greater than 85 decibels can cause ear...
Two types of sounds produced by the cichlid fish , are recorded and analysed. A br-r-r sound, with a main frequency of 200 Hz and a chewing sound with a main frequency of 6,000-10,000 Hz are produced during threatening; the former sound can also be heard during quivering. No sound...

Sounds are produced, by objects that vibrate (振动), at a rate that the ear can detect. This rate is called frequency and is measured in hertz (赫兹), or vibrations per second. Most humans can hear sounds between 20 and 20,000 hertz, while dogs can hear high pitched sounds (高频声音...
