velocity level การใช้

• In applications involving sound, the particle velocity is usually measured using a logarithmic decibel scale called particle velocity level.
• The individual zones, position rings, and velocity levels can be used to trigger different instruments, effects parameters, or volume changes.
• Currently a variety of factory ammunition loadings are available in . 44 Special, including bullet weights of 135, 165, 180, 200, 240, 246, and at various velocity levels.
• Examples are the various types of sound level : sound power level ( literally, the level of the sound power, abbreviated SWL ), sound exposure level ( SEL ), sound pressure level ( SPL ) and particle velocity level ( SVL ).
• In 1982, Yamaha Corporation introduced the Disklavier PRO models are capable of capturing and reproducing " high-resolution " piano performances of up to 1024 velocity levels and 256 increments of positional pedaling using Yamaha's proprietary XP ( Extended Precision ) MIDI specification.
• With its strengthened case and increased pressure ceiling, the . 327 Federal Magnum reaches the velocity levels of the . 357 Magnum, if not the same power, with velocities of up to 1400 ft / s ( 420 m / s ) from the 3 1 / 16 " barrel of the first-edition Ruger SP101.
