During the COVID-19 pandemic, JLab donated 3,000 headphones in its home county of San Diego to help distance learning. "At a time when many students are lacking the equipment necessary to successfully participate in distance learning while at home during the COVID-19 pandemic, local company JLab Audio has answered the need and donated 3,000 pairs of its neon on-air headphones to San Diego ...
Thomas Jefferson National Accelerator Facility (TJNAF), commonly called Jefferson Lab or JLab, is a US Department of Energy National Laboratory located in Newport News, Virginia. [ 1 ] Since June 1, 2006, it has been operated by Jefferson Science Associates, LLC, a limited liability company created by Southeastern Universities Research ...
Focal Opal 19ti. Focal-JMlab is a French company that has been designing and selling high fidelity audio systems since 1979. Based in Saint-Étienne, the company manufactures loudspeakers for the home, speaker drivers for automobiles, headphones, professional studio monitors, as well as outdoor speakers and those dedicated to yachts.
Clipping (audio) The altered peaks and troughs of the sine wave form displayed on this oscilloscope indicate the signal has been "clipped." Clipping is a form of waveform distortion that occurs when an amplifier is overdriven and attempts to deliver an output voltage or current beyond its maximum capability. Driving an amplifier into clipping ...
Total harmonic distortion. The total harmonic distortion (THD or THDi) is a measurement of the harmonic distortion present in a signal and is defined as the ratio of the sum of the powers of all harmonic components to the power of the fundamental frequency. Distortion factor, a closely related term, is sometimes used as a synonym.
Active noise control (ANC), also known as noise cancellation (NC), or active noise reduction (ANR), is a method for reducing unwanted sound by the addition of a second sound specifically designed to cancel the first. The concept was first developed in the late 1930s; later developmental work that began in the 1950s eventually resulted in ...
Tube sound (or valve sound) is the characteristic sound associated with a vacuum tube amplifier (valve amplifier in British English), a vacuum tube-based audio amplifier. [1] At first, the concept of tube sound did not exist, because practically all electronic amplification of audio signals was done with vacuum tubes and other comparable ...
Noise reduction. Noise reduction is the process of removing noise from a signal. Noise reduction techniques exist for audio and images. Noise reduction algorithms may distort the signal to some degree. Noise rejection is the ability of a circuit to isolate an undesired signal component from the desired signal component, as with common-mode ...
