The sound level of the signal would be 40 dBHL. The dBHL unit is used to specify sound levels relative to an individual's hearing threshold, while the dBHL unit is used to specify sound levels relative to a standard reference sound pressure level. When the sound level in dBHL is equal to the sound pressure level in dBSL, the sound level of the signal is the same as the signal level presented.
One is the hydrophone, used to pick up sound waves underwater.
No.When used before a vowel sound, "the" has a long E sound.(The animal is wild.)When used before a consonant, "the" has a schwa or unstressed sound (thuh).(The wild animal is loose)

A lion's roar can be heard over 10km away, as it is a powerful sound signal used by males to communicate their presence and territory to potential rivals and mates.
Signal is a noun (a signal) and a verb (to signal).
There is no real reason. In the UK's old analogue system AM was used for picture and FM used for sound. In France they used the opposite system, FM for picture and AM for sound. Everything is going digital now, so does not apply, the RF signal is a FSK data signal.
falseanswer 2. Over a small region, an 'antiphase signal' can be used to cancel out a sound.

A unit used to measure the intensity of a sound or the power level of an electrical signal. Someones voice could raise by a decibel.It is used to measure the sound intensity and loudness.
The term recording refers to a signal that is used to encode something such as a picture or sound that has been recorded.
AS the board and CPU execute programs, they send associated sound signals to the sound card on your computer. The sound card converts the digital signal into analogue and sends that signal to the external port(s). Assuming a speaker is plugged in, the signal is carried over wire to the speaker (or headphone) speaker, where a electromagnet is used to move the speaker cone. This produces sound which can be heard.
