Sound is a time dependent pressure variation in air. A microphone translates this to a varying voltage on a wire. Analog recorders record this signal by storing the varying voltage on magnetic tape as a varying magnetization in a strip of tape coated with a magnetic material. Digital recorders first digitize the signal by rapidly taking samples of the voltage, perhaps 30000 samples every second. Each sample is then digitized by a device called an A-D converter. The digital numbers from this converter are stored digitally in various ways, eg, in pits cut in a disc by a laser. The A-D converter is the heart of the digitization process. Typically it is a chip sold by one of several companies. How this works is too complicated for the space we have here. Look at this reference for more info. http://en.wikipedia.org/wiki/Analog-to-digital_converter

How is sound digitised?

Sound is digitized through a process called analog-to-digital conversion. This involves capturing the sound waves using a microphone, converting them into electrical signals, and then sampling and quantizing these signals into discrete numerical values that can be stored and processed digitally. This results in a digital representation of the original sound.


What converts your voices sound waves to digital signals?

A microphone converts voice sound waves into electrical signals, which are then digitized by an analog-to-digital converter (ADC) to produce digital signals. These digital signals can then be processed and transmitted digitally.


What is the mechanism of digitized sound?

A chip called an Analogue to digital converter (ADC) is used to convert sound waves in the form of analogue electrical impulses, into numeric values which can then be processed by the computer. Conversely, a chip called a digital to analog converter (DAC) does the reverse. The quality of the sound recorded is goverend by two constants , this is the sample rate and the bit depth. The sample rate is the number of samples of a sound taken per second. For instance a CD is sampled at 44kHz or 44,000 samples per second. The bit depth describes the maximum value of a number used to store the amplitude of a sound. The greater this value the greater the change between silence and the maximum sound value stores or greater dynamic resolution. In the case of CD's 16 bit or a value between 0 and 65535.


What is the difference between sound power and sound pressure, and how do they relate to each other in the context of acoustics?

Sound power is the total amount of energy emitted by a sound source, while sound pressure is the force exerted by sound waves on a surface. In acoustics, sound power is the source of sound, and sound pressure is the measure of how that sound power is transmitted through a medium. Sound power and sound pressure are related in that sound power generates sound waves, which then create sound pressure as they travel through a medium.


What is the relationship between sound power and sound pressure in acoustics?

In acoustics, sound power is the total amount of energy produced by a sound source, while sound pressure is the force exerted by sound waves on a surface. The relationship between sound power and sound pressure is that sound power determines the potential loudness of a sound, while sound pressure measures the actual intensity of the sound at a specific point. Sound power and sound pressure are related, but they are not directly proportional to each other.

How telkom uses fiber optics to transmit sound than the copper cables?

Hi The sound is converted from analogue signal into a digital format and then transmitted with other digitized voice signals across the fibre. Next the digital signal are separated and converted back to analogue signal. regards Philip
