Why is reflected sound louder from the closed end of a long pipe than from a cliff at the same distance from the observer?

Because the sound energy (air compressions/rarefactions) can't escape from the pipe, while a lot of the sound energy can disperse sideways on its way there and back to a cliff. (You don't have to stand directly in front of someone to hear them speak).

How many decibels does a fan make?
That depends how close you measure to the fan. The closer - the louder! The distance is very important if you measure with a sound pressure level meter.
What is the highest decibel level a rat can emit?
The decibel level of a rat depends on the measurig distance to the rat. The closer you are to the mouth of the rat the louder the noise you can measure will be.
What is sound louder than?
Amplitude is a measure of the size of sound waves. It depends on the amount of energy that started the waves. Greater amplitude waves have more energy and greater intensity, so they sound louder. As sound waves travel farther from their source, the more spread out their energy becomes.
How many decibels are produced by a normal conversation?
That depends how close you measure to the mouth speaker. The closer - the louder! The distance is very important if you measure with a sound pressure level meter. A conversation in 1 meter distance may have 60 decibels.
Does sound get quieter or louder through medium?
Sound does indeed get quieter through medium. The level of loss depends on the medium that is used, and as the square of the distance from source.
What happens to a wave if it is reflected from a more rigid medium?
it becomes louder
Is shooting a gun in a house louder or quieter than outdoors?
Louder because you are more in closed so it echoes more.
Are the 5.56x45 and 7.62x39 both equally loud just a different pitch in the sound and how loud are they compared to a 308 and which is louder at a distance a 5.56 NATO or a 7.62x39?
In my opinion, the 5.56 and 7.62x39 are very closwe in noise level, the 7.62 being a bit louder. The .308 is about 25% louder. Distance does not matter.
What is a vacuum not a vacuum cleaner?
That depends on the distance to the vacuum cleaner. The closer, the louder.
How does resonance work when you sing in the shower?
The bathroom is closed and sometimes small,as you sing the sound waves hit the walls more frequently causing the wall to vibrate,since walls are parallel to each other.the reflected sound hit each other,there by causing the wall to vibrate at your natural frequency and louder sound is transmitted.
Is sound louder in a room with its door open or with its door closed please state ur source too?
Sound is not audibly louder in a room with the door open or closed. If I had a volume meter I might be able to measure the sound being slightly louder with it closed because the sound would reflect off a closed door but leave through an open one, but you'll never hear it. I determined this experimentally. First I closed the door to the room and played some Iron Maiden with my speakers turned up halfway. Then I opened the door to the room and played the same song at the same volume setting. It didn't get any quieter in there. The real effect, of course, is OUTSIDE the room. If I open the door and play Maiden, the neighbors hear it better than if I keep it closed and play them.

How many decibels is a drum kit?
A drum kit is no decibels. The decibels depends how close you measure to the bat. The closer - the louder! And the louder you play the more decibels you get. The distance is very important if you measure with a sound pressure level meter.
What is the sound quality of a harp?
The decibels depends how close you measure to the harp. The closer - the louder! And the louder you play the more decibels you get. The distance is very important if you measure with a sound pressure level meter.
Does the Doppler effect have anything to do with medicine?
No. It has to do with sound or light waves (or any other if there is). It is the apparent change in frequency of a wave as the observer and source move toward or apart from each other. EX: think of a car when it passes by. the frequency of the wave changes and it gets louder then quieter. You would be observer and the source would be wherever the sound comes from. Hope this helps :)
