Sampling rate is a very complex thing to understand. Sampling rate does not have a specific volume, but it mainly depends on what was recorded or how it was recorded. Also what sampling rate was used may even be involved.
A digital recording is governed by two things, the sample rate and the bit depth.
A sound wave is determined by two things also, the frequency of the signal and it's amplitude (How loud it is at that instant per wave). To convert from a sound wave to a digital format we have to examine the current frequency and amplitude and convert these analogue values to digital ones.
The rate at which we do this is called the sample rate.
At the same instant we sample the volume which is stored in a value called the bit depth. The bit depth relates to a binary value of which for instance 16 bit represents a value in decimal from 0 - 32765. Obviously the bigger the bit depth the larger the value number can be stored & therefore the higher resolution of the amplitude waveform is available.

How does the sampling oscilloscope increase the appearent frequency response of an osciloscope?
A: A sampling scope is not real time scope but rather a hi frequency rate of sampling which benefit the observer
What converter digitizes sound waves into a series of numbers?
This process is called PAM [pulse Amplitude modulation] Sampling: here is a Shout-out for the actual PAM Sampling rate - meanwhile assume a PAM sampling rate of once per millisecond: this means that each millisecond the natural audio acoustic wave's Amplitude is sampled/determined and the Amplitude of this acoustic wave is Quantified by another process called Digitization.
Which of the following describes the number of times an analog wave is measured each second during an analog-to-digital conversion?
Sampling Rate.
What is volume and rate considered when delivering a brief?
The area of consideration when delivering a brief of volume and rate is a verbal consideration. This is such because delivering a brief is oral.
Why do biologists use sampling?
Biologists use sampling in their work because of two main reasons. Studying all the organisms in a population will be time wasting and the exercise will be expensive.
What is the sampling rate in Hz?
Sampling rate is a defining characterstic of any digital signal. In other words, it refers to how frequently the analog signal is measured during the sampling process. Compact disks are recorded at a sampling rate of 44.1 kHz.
What uis the sampling rate for PCM if the Frequency ranges from 1000 to 4000 Hz?
As we know that the sampling rate is two times of the highest frequency (Nyquist theorm) Sampling rate=2 Nyquist fs=8000hz/8khz
What is sampling rate of cds?
44.1kHz
Sampling rate unit?
what is the rate unit of 1,700 and 40
What is sampling rate in audio digitization?
Sampling rate or sampling frequency defines the number of samples per second (or per other unit) taken from a continuous signal to make a discrete or digital signal.
What is up sampling and down sampling?
Upsampling is the process of increasing the sampling rate of a signal. For instance, upsampling raster images such as photographs means increasing the resolution of the image.In signal processing, downsampling (or "subsampling") is the process of reducing the sampling rate of a signal. This is usually done to reduce the data rate or the size of the data.
What is the unit of measurement of the sampling rate when recording sound waves?
The sampling rate is expressed in units of either "samples per second" or "Hertz (Hz)".
If the frequency spectrum of a signal has a bandwidth of 500 Hz with the highest frequency at 600 Hz what should be the sampling rate?
The Nyquist Therorem states that the lowest sampling rate has to be equil to or greather than 2 times the highest frequency. Therefore the sampling rate should be 400Hz or more.
How does the sampling oscilloscope increase the appearent frequency response of an osciloscope?
A: A sampling scope is not real time scope but rather a hi frequency rate of sampling which benefit the observer
What is sampling thearm cocerning the rate of sampling required for analog signal?
It states that for satisfactory representation of the sampled signal the sampling frequency must be atleast equal to twice the highest input freq, which is called nyquist sampling. If its less than twice, undersamplin occurs resulting in distortion.
What does the sampling theorem tell us concerning the rate or sampling required for an analog signal?
You must sample at 2 x the rate of the analog signal (2 x the analog signal frequency).
What is targeted sampling in research studies?
I would like to sample the signal Xa(t) =1+cos(10 *pi*t) using sampling frequency fs=8 Hz. How can I calculate this? ANSWER: Your signal has a frequency component of 5hz (from the equation: 2*pi*f*t = 10*pi*t, therefore f=5). The Nyquist rate for this signal (the minimum sampling rate required to reconstruct the signal) is then 10Hz, and even at that rate the amplitude of the sampled signal will be reduced unless you can somehow synchronize the sampling with the peaks/troughs of the cosine signal. If you sample at 8Hz you will not be able to reconstruct the signal at all.
