How much greater is the sound pressure level of a 100 dB siren than an 80 dB alarm clock How much louder would most people perceive the siren to be?
The sound pressure level of a 100 dB siren is 100 times greater than that of an 80 dB alarm clock. Most people would perceive the 100 dB siren to be around twice as loud compared to the 80 dB alarm clock due to the logarithmic nature of the decibel scale and human perception of sound intensity.

What determines the volume of a sound?
The volume of a sound is determined by the amplitude of the sound wave. Amplitude refers to the maximum displacement of particles in a medium from their rest position when a sound wave passes through it. The greater the amplitude of the sound wave, the louder the sound will be perceived by our ears. This is why sounds with higher amplitudes are perceived as louder than sounds with lower amplitudes.
What is the lowest frequencey that a human can hear?
The lowest frequency that a human can typically hear is around 20 Hz. Below this frequency, most people may not perceive the sound as a distinct pitch but rather as a sensation of pressure or vibration.
Why is it louder when the sound is at night?
At night, the ambient noise levels are typically lower due to fewer people being active and background noise from traffic decreasing. This can make sound sources appear louder in comparison. Additionally, sound waves can travel further at night due to cooler air temperatures, allowing the sound to carry over longer distances.
A sound waves amplitude corresponds to the sounds what?
Usually, people are asking as if there is just "the" amplitude in sound waves in air. The loudness perception of a sound is determined by the amplitude of the sound waves − the higher the amplitude, the louder the sound. Which amplitude of sound (sound amplitude) do you mean? There are: amplitude of particle displacement ξ, or displacement amplitude amplitude of sound pressure p or pressure amplitude amplitude of sound particle velocity v, or particle velocity amplitude amplitude of pressure gradient Δ p, or pressure gradient amplitude. Furthermore, think of the amplitude of the oscillation of a string. The maximum magnitude of the deflection of a wave is called amplitude. Look at link: "What is an amplitude?"
Which is louder 55 dba or 51 dba?
About the same as a normal conversation between two people standing three feet apart.
Why do some people laugh louder than everyone else?
Some people may laugh louder than others due to various factors such as their personality, cultural background, or environment. It can also be influenced by how they perceive humor and their level of comfort and confidence in expressing their emotions.
Do hearing aids help people hear a greater range of pitch or just make the sound louder?
I am very sorry to tell you that it just makes the sounds louder. It would take a lot of technology to make it a higher pitch. I even tried it by myself and it didn't work.

What is the best way to perceive other people?
Perceive other people as other aspects of yourself.
How do you know how men perceive you?

People perceive the way they do because they are controlles by their own will power and choices. They also have their own beliefs and their own interpretation of events and words. All these affect they way they perceive things.
How loud do people fart?
The loudness would more likely be based on the pressure of the gas inside of the body. The pressure relies on the types of food that you eat. Being that the foods that cause this are usually consumed by people of a larger scale, the "myth" that fat peoples farts are louder than average can be understandable.
Why do some people walk rather than run when its raining?
The velocity of the rain hitting the person running is greater than when the person is walking. This is felt on the human skin as non-periodic pressure. The faster the running, the greater the pressure - people feel this as increased "pain" after a certain point.
How loud do fat people fart?
