What happens to frequency as amplitude increases? How does the frequency of sound change when the source is moving? If the temperature of wire in a sonometer is increased, what happens to the frequency of sound heard? When you decrease the frequency of the wave, what happens to its wa...
What happens when you squeeze a bottle with half water, half air? With the in altitude, there is a simultaneous in gravity, which in turn atmospheric pressure. a) decrease; increase; decreases b) increase; decline; increases c) decrease; increase; increas...
While sound is measured in terms of frequency, amplitude, and wavelength, defining the pitch, loudness, and tone of what we hear, sonic often refers to applications or effects that operate at or above the speed of sound. This includes sonic speed, which is the speed at which sound waves ...
Think of a basic square wave like the one you might use to build a lead or bass sound in your synth. Even if you change its frequency or amplitude, the wave’s basic shape will stay the same. The opposite is anaperiodicsound like the cymbal crash. Even if you produced a sustained to...
根据“but amplitude—the height of the wave—increases greatly, leading to the huge wall of water along coastlines”可知,振幅,即波的高度,大大增加,increase表示“增加”,but表转折,可推知上半句是说波长减小,所以decreases表示“减小,减弱”。故选B。【小题3】段落大意题。根据该段“tsunami warning ...
performance of audio systems, so we need to incorporate subjective impressions into our assessments somehow. Finding appropriate metrics that correlate the listener’s experience of sound quality with things that can be objectively measured has been the goal of researchers in this field for many ...

The perception of sound is subjective and can vary greatly among different listeners. It depends on the physical properties of the sound waves, including frequency, amplitude, and phase. On the other hand, audio is often manipulated to enhance quality or to suit specific needs, through techniques...
reflected in completely different directions. this type of reflection is called diffused reflection and is what enables us to see non-shiny objects. diffused reflection multiple reflection a single image is formed when an object is placed in front of a mirror. what happens if we use two mirrors...
If we make tap width as before the redistributing (tap width at the part A of the picture), noise level will 2 times lesser. Because square of noise is constant. It happens on computer display, when tap width have same pixel width on a screen. ...
