Signals - Adding Decibels - The logarithmic decibel scale is convenient when adding signal values like sound power, pressure and others from two or more sources.Scales of Objects - The relative scale of objects.Phonetic Alphabet - The phonetic alphabet used in international aircraft communications.Outdoor Ambient Sound Pressure Levels - Outdoor ambient sound pressure levels (dBA) in rural and urban business and industrial environments with or without limited traffic.Noise generated in Air Ducts - Estimate noise generated by air flow in ducts.Maximum Sound Pressure Levels in Rooms - Maximum recommended sound pressure levels in rooms like kindergartens, auditoriums, libraries, cinemas and more.Logarithms - The rules of logarithms - log 10 and log e for numbers ranging 1 to 1000.Decibel A, B and C - Sound pressure filters that compensates for the hearing sensed by the human ear.Miscellaneous - Engineering related topics like Beaufort Wind Scale, CE-marking, drawing standards and more.Noise and Attenuation - Noise is usually defined as unwanted sound - noise, noise generation, silencers and attenuation in HVAC systems. ![]() Acoustics - Room acoustics and acoustic properties, decibel A, B and C, Noise Rating (NR) curves, sound transmission, sound pressure, sound intensity and sound attenuation. ![]()
