1.Generating or using waves or vibrations with frequencies below that of audible sound.
3.The Comfortness of passenger lift is a principle requirement of the quality of a lift,the type TKS10 lift manufactured by a certain factory was throughly investigated, reasonable proposals to diminish the vibration and improve the comfortness of the car were suggested to the manufacturer.
4.Digital audio Sound waves generate air pressure oscillations that stimulate the human auditory system.
5.Chapter 4 included three major contents. (1) The maximum acceleration response spectrum method,which presented a simplified method to evaluation long-span floor vibration response under pedestrian exciting.
6.An audio(sound) wave is a one-dimensional acoustic(pressure) wave. When an acoustic wave enters the ear， the eardrum vibrates， causing the tiny bones of the inner ear to vibrate along with it， and sending nerve pulses to the brain. These pluses are perceived as sound by the listener. Audio waves can be converted to digital form by an ADC (Analog Digital Converter). An ADC takes an electrical voltage as input and generates a binary number as output. Music， of course，is just a special case of general audio，but an important one. The representation， processing，storage, and transmission of such audio signals are a major part of the study of multimedia systems.

8.Sounds are produced by objects that vibrate at a rate that the ear can detect.
9.This picture is significantly different from the previous conclusion that the interfacial water molecule orientation varies over a broad range within the ultrafast vibrational relaxation time, the only direct experimental study concluded for ultrafast and broad orientational motion of a liquid interface by Wei et al. (Phys. Rev. Lett. 86, 4799, (2001)) using single SFG experimental configuration.
10.This probably helps them to work out from which direction the vibrations are travelling -- rather as a person might stick a finger first in one ear and then in the other to work out the direction that a sound is coming from.
