Because our brains lack the capability to de-code digital signals. Therefore, any digital sound must be converted to analogue (and be within a specific frequency range) for us to hear it.

It is "An" hour, not a hour. The "an" comes before every vowel sound, not every vowel.
Sound energy comes from when you are speaking to your friends, a bee buzzing, boiling water, the horn of a car, clapping your hands, stomping your foot hard against the floor and many more.Anything with sound is a good example of sound energy.Examples: laugh, scream, yelling,radio
There are several things that you want to look out for when evaluating a person's speech. What message is the speaker trying to convey? Is it clear, or does it digress? The speech should also have a clear beginning, middle, and conclusion. How good is the speaker's vocabulary? Does his speech sound natural? Watch out for bad speaking habits, such as 'um's, 'ah's, wide pauses, repetition. The speaker should always make eye contact with the audience, and stand straight. Posture is important - it conveys confidence.
Yes. The "275W" is the maximum power that the speaker can handle at its input. The "120W" is the maximum undistorted power that the amp can deliver in the loud spots with the volume wide open. So the amplifier will never overdrive the speaker. The impedances of the speaker and amp-output should match. If one of them is marked "4 ohms", then they both should be. If they're not the same, then . . . -- the speaker may not sound as 'crisp' as it should. -- the amplifier may not deliver as much undistorted power as it should. -- the amplifier may not run as cool as it should. -- with an extreme mismatch and extended loud spots played at high volume, the amplifier may even be damaged.
No, it measures a computer's similarity to human intelligence. If it can make an answer to a random question and sound human, then it's passed.
