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.
Yes, a megaphone is typically shaped like a cone. This conical design helps to amplify sound by directing the sound waves produced by the speaker's voice outward in a focused manner. The wider end of the cone serves as the opening that projects the sound, while the narrower end is placed near the speaker's mouth. This shape enhances the volume and clarity of the sound.
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.
The color coding of speaker wire can vary, but typically, the white or lighter-colored wire is used for the negative connection, while the solid color wire (often black or red) is used for the positive connection. It's essential to check the specific wiring conventions for your speaker system, as some manufacturers may use different standards. Always ensure that you connect the wires consistently to maintain proper phase and sound quality.
AD is Analog to Digital conversion the use is to do digital measurements of analog voltages and currents, a computer soundcard is an AD converter that convert analog sound to digital sound so that it can be played on a computer, and DA is the opposite, digital to analog conversion, the digital sound on the computer is converted to analog sound to drive a speaker or headphone
That would be analog. A speaker is not just on or off, and its range varies as the voltage changes. Sound cards use a D/A converter to convert digital data to audible sound.
No. Sound has to be converted from analog to digital for use by a computer, not the other way around. It is converted to analog so amplifiers and other analog equipment can use it and so you can hear it.
So you can hear sound from the computer.
I activating my speaker.
The process of converting analog sound into digital code is called analog-to-digital conversion (ADC). During this process, the continuous analog signal is sampled at specific intervals and quantized into discrete values, which can then be represented in binary code for computer processing. This allows the analog sound to be stored, manipulated, and played back by digital devices.
No, the sound card is attached to the motherboard of the computer.

speakers is sound which is actually data
The sound card functions by converting digital data into analog information. It also converts analog data into digital data. The digital signal processor inside of the sound card is responsible for this.
they let the sound out so u can hear music or sound
