SpletSilencer is the earlier, more traditional term for such noise reduction devices. Recently, however, suppressor has gained currency in connection to American gun rights organizations. The US National Firearms Act (NFA) of 1934 defined silencers and established regulations limiting their sale and ownership. Both the US Department of … SpletThe amplitude of a sound wave determines its intensity, which in turn is perceived by the ear as loudness. Acoustic intensity is defined as the average rate of energy transmission per unit area perpendicular to the …

SpletAs with pitch, the loudness of a sound is a subjective measure – it depends on the person. You may have an elderly relative who listens to the TV at what seems to be ear-shattering volume to you, and yet is comfortable for their ears. The same sound is judged to be of different loudness by two people. radix screws

SpletPhysics. Physics questions and answers. Part A- Variation in the speed of sound Sound is a longitudinal wave, and its speed depends on the medium through which it propagates. In air, sound travels at 343 m/s. In an experiment, you observo a sound with a frequency of 500 Hz and a wavelength of 6.4 m. What is the speed of sound in this differont ... SpletThe loudness of sound depends on its amplitude. The loudness of sound is proportional to the square of the amplitude. A roar of a lion is louder than a woman’s voice. The loudness of sound is measured in Decibel (db). If loudness exceeds 80 db, then the sound becomes physically painful. SpletCorrect option is C) The intensity or loudness of a sound depends upon the extent to which the sounding body vibrates, i.e., the amplitude of vibration. A sound is louder as the … radix smartclass 12.15.1.513
