Noise is usually defined as unwanted sound - noise, noise generation, silencers and attenuation in HVAC systems.
Human physiology, air quality and comfort temperatures, activity and metabolic rates, health effects of carbon monoxide and more.
Estimate structures natural vibration frequency.
Sound pressure filters that compensates for the hearing sensed by the human ear.
Human activities like walking, running and dancing - and operating machines - can introduce floor vibrations due to resonance.
Effects of low-frequency vibrations on building constructions.
Acceptable noise - dBA - level at typical common locations.
Comparing Noise Criterion (NC, NCB, RNC) to Noise Rating (NR) and dB(A).
Exposure to noise should be controlled so that it is less than a maximum combination of exposure level and duration.
pH in human materials like blood, salvia and more.
Acoustic power of sound per unit area.
Sound Pressure is the force of sound on a surface perpendicular to the propagation of sound.
Change in sound pressure level and the subjective human perception.
