Distortion Distortion is also used as a musical effect, particularly with electric guitars. The addition of noise or other outside signals (hum, interference) is not deemed distortion, though the effects of quantization distortion are sometimes deemed noise. A quality measure that explicitly reflects both the noise and the distortion is the Signal-to-noise-and-distortion (SINAD) ratio.

What Is Intermodulation Distortion (IMD)? What Is Intermodulation Distortion? Intermodulation Distortion is often found as an amplifier or pre-amplifier specification (but can exist for other audio components like speakers, CD/DVD/media players, etc.) that quantifies the non-harmonic frequencies added to an input signal.

What does distortion mean? Rating Newest Oldest. Best Answer: In cartography, a distortion is the misrepresentation of the area or shape of a feature. The Mercator projection, for example, distorts Greenland because of its high latitude, in the sense that its shape and size are not the same as those on a globe.

Ultrasound Ultrasound is sound waves with frequencies higher than the upper audible limit of human hearing. Ultrasound is no different from 'normal' (audible) sound in its physical properties, except in that humans cannot hear it. This limit varies from person to person and is approximately 20 kilohertz (20,000 hertz) in healthy, young adults. Ultrasound devices operate with frequencies from 20 kHz up to several gigahertz.

Voice Disorders Voice Disorders. A voice disorder is when the voice has a problem with pitch, volume, tone, and other qualities. These problems occur when the vocal cords don't vibrate normally. Your voice is the sound that air makes when it is forced out of your lungs and passes over your vocal cords.n order to make normal speech, your vocal cords need to touch together smoothly inside your larynx. Anything that interferes with vocal cord movement or contact can cause a voice disorder. Many voice disorders can be cured with treatment when diagnosed early.

Delay (audio effect) Delay is an audio effect which records an input signal to an audio storage medium, and then plays it back after a period of time. The delayed signal may either be played back multiple times, or played back into the recording again, to create the sound of a repeating, decaying echo.

Guitar amplifier Power-tube distortion is required for amp sounds in some genres. In a standard master-volume guitar amp, as the amp's final or master volume is increased beyond the full power of the amplifier, power tube distortion is produced. The power soak approach places the attenuation between the power tubes and the guitar speaker.

Kelly Ripa Diagnoses Herself With Mysterious Neurological Disorder Hatred of Sound. Misophonia literally means “hatred of sound” and is a form of decreased sound tolerance. The term was coined by American neuroscientists Pawel and Margaret Jastreboff in 1991. For those with misophonia, everyday sounds can lead to extreme reactions.

Studio Condenser Microphones A Pad refers to attenuation, or a lowering of volume, output or loudness. A -10 pad reduces the sensitivity of the microphone by 10 decibels so it can withstand louder sounds like drums, cymbals, screaming vocalists and other awfully loud things. Some mics may have -20 pads or -15 pads.

- Total harmonic distortion. The total harmonic distortion, or THD, of a signal is a measurement of the harmonic distortion present and is defined as the ratio of the sum of the powers of all harmonic components to the power of the fundamental frequency. THD is used to characterize the linearity of audio systems and the power quality of electric power systems.

The Compressor is one of the most misunderstood effects of all â hereâs what it does, and why you might need one Put simply, a compressor reduces dynamic range. The dynamic range is the range from the quietest point to the loudest point in a given piece of audio. So, if that was, say, a guitar performance, that would most likely be from silence up to the loudest bit of the performance.

- The amount of the nonlinear distortion is measured using a sine wave as a test signal. THD is defined as the ratio of the geometric mean of the harmonic components (v2, v3, v4, v5, ... ) and the fundamental component (v1). It is expressed in dB or %, and lower numbers are considered to be better.DSSF3's THD analyzer is designed for measuring the distortion of input/output systems, like an amplifier and a soundcard. Internal signal generator is used to feed a test signal to the device under test, and its output is measured.Basic measurement configuration is as follows.f the soundcard's input and output are connected directly (R ch: ----), distortion of the soundcard itself can be measured. This is called a loopback test, and is very important to perform an accurate measurement.

- The harmonic distortion of the signal source and the dynamic range of the spectrum analyzer limit the quality of the measurement. However, the signal source is often the limiting factor, with harmonic distortion performance on the order of 30 to 50 dB below the fundamental. In your test setup, you are likely to use passive devices such as cables, filters or switches between your source and the DUT. The accuracy of the signal level at the DUT iseffected by the use of these components.

What does distortion mean? First the dictionary definition to understand the concept: A distortion is the alteration of the original shape (or other characteristic) of an object, image, sound, waveform or other form of information or representation. Distortion is usually unwanted, and often many methods are employed to minimize it in practice.

Overview Pancreatitis occurs when digestive enzymes become activated while still in the pancreas, irritating the cells of your pancreas and causing inflammation. With repeated bouts of acute pancreatitis, damage to the pancreas can occur and lead to chronic pancreatitis. Scar tissue may form in the pancreas, causing loss of function. A poorly functioning pancreas can cause digestion problems and diabetes.

Electronic Sound Reproduction After the microphone detects the sound, it goes through some electronics and is then reproduced and transmitted through loud speakers or headsets that consist of tiny speakers. Just like a microphone, the speakers also attenuate various frequencies and distort the sound coming out.

ABOUT COMPRESSION WHAT IS A COMPRESSOR? A compressor is a special kind of amplifier, used to reduce dynamic range. It's basically an automatic volume control, making the quiet parts of a track louder and reducing over-loud peaks for a more consistent, even sound. The most basic parameters of a compressor are gain, threshold, ratio, attack and release:

Distortion This is the cause of the droop seen on the top of the pulses. This pulse distortion can be very significant when a train of pulses must pass through an AC-coupled (high-pass filtered) amplifier. As the sine wave contains only one frequency, its shape is unaltered.

Total harmonic distortion Like the THD measurement, this is a ratio of RMS amplitudes, and can be measured as THD F (bandpassed or calculated fundamental as the denominator) or, more commonly, as THD R (total distorted signal as the denominator). Audio Precision measurements are THD R, for instance.HD+N means total harmonic distortion plus noise. This measurement is much more common and more comparable between devices. It is usually measured by inputting a sine wave, notch filtering the output, and comparing the ratio between the output signal with and without the sine wave:
