Ambient noise is background noise that is always present. The nature and level of this sound can vary considerably, sometimes turning into a distraction or a nuisance. Sound meters are used to establish ambient noise levels for the purpose of researching it and addressing specific complaints about...
Context awareness:Ambient intelligence is acutely attuned to the context in which it operates. Through the use of sensors and data collection, it gathers information about the environment, users, and their activities. It understands and adapts to factors such as location, time, temperature, light, ...
Sound masking makes a building seem quieter by raising the ambient noise level of an environment and making speech noise less intelligible and therefore less distracting. Sound masking is an ambient sound, similar to the sound of airflow, that’s specifically engineered to the frequency of human ...
Ambient seismic noise based monitoring reveals feeble perturbations of the subsurface.Mechanical perturbations are related to temperature, stress, hydrological changes, or to damage.Seismic noise from rivers and glaciers reveal new sources of seismic activity.Glacier and fluvial seismology shed a new light...
The purpose of a guitar amplifier is to take the low-level output from an electric guitar and make it sound good. It has nothing to do with accuracy (which is irrelevant in this application), and everything to do with aesthetics. We simply want a good sound from this signal amplifier, ...
What is Signal to Noise Ratio? Signal-to-Noise Ratio (SNR) is used to measure the ratio of the desired signal to the background noise level, helping us evaluate the quality and reliability of a signal. In simple terms, SNR quantifies the strength of a signal relative to the level of ...
Pink Noise Pink noise is a constant sound in the background. It filters out things that distract you, like people talking or cars going by, so they don’t interrupt your sleep. You may hear it called ambient noise. Like white noise, it’s a steady background hum that may give you a...
Marked by or showing common sense and good judgment; levelheaded A sound approach to the problem. Noise The auditory experience of sound that lacks musical quality; sound that is a disagreeable auditory experience; Modern music is just noise to me Sound Based on valid reasoning; having no logic...
You’ve seen the term “active noise cancellation” used to promote wireless headphones, but what is it exactly? When you have no choice but to be exposed to constant ambient noise, active noise canceling (ANC) headphones can save the day (and your hearing!). ...
Large voltages must be stepped down to the nominal digitizing level. There are sensors for this, including potential transducers (PTs) which can divide the thousands of volts on an electrical transmission line down to a safe level. The output of a PT is then fed into the voltage signal condi...
