The intensity of a sound is determined by the rate and density of energy transfer. The larger the amplitude, the greater the intensity, and the louder the sound.

What is two properties of sound?
Examples: frequency, intensity, wavelength.
What are two factors that affect sound quality?
Speed of Sound and frequency
What two factors dos loudness depend on?
The loudness of a sound depends on the amount of energy it takes to make the sound and the distance from the source of the sound
What two things affect loudness?
The speed of sound is slower at higher altitudes because the air temperature is lower. The greater the amplitude, the louder the sound. It is your perception of the energy of a sound. What two factors affect the loudness of a sound
What factors determines the strength of the frictional force between two surfaces?
how hard the surfaces push to gether the types of surfaces involved
What two factors determine the intensity of sound?
The intensity of a sound is determined by the rate and density of energy transfer. The larger the amplitude, the greater the intensity, and the louder the sound.
Which two factors sound intensity?
Reverberation time, loudness, Focusing, interference, echo, echelon effect, resonance, noise
What is two properties of sound?
Examples: frequency, intensity, wavelength.
What two factors determine whether noise is hazardous to hearing?
Intensity and duration
What determines a matter state of matter?
Temperature and pressure are two factors.
What are two factors that determin speed?
distance and time, determines speed.
What is the difference between loudness and intensity?
Sound intensity or acoustic intensity can be calculated from the objective measurement of the sound pressure. The loudness is a psycho-acoustic subjective feeling, which is difficult to measure.
What two factors determines the density of a fluid?
The density is the mass divided by the volume.
What two factors determines alleles an organism ends up with?
Dominant and recessive
What are two factors that affect sound quality?
Speed of Sound and frequency
What are the two cues that help us localize sound are?
Arrival time and intensity difference. Due to the different spacial positioning and orientation of the ears, a sound wave will arrive at each ear at slightly different times and with slightly different intensity. For example, if a sound originates to the right of a person, the sound will reach the right ear first and the right ear will experience a greater intensity. These very small differences are integrated in the nervous system and are manifested as the ability to localize sound.
What are decibels a measure of?
The intensity of sound is measured in a unit called the decibel (dB), which describes the relative intensity of a sound based on an algorithmic decibel scale containing values ranging from 0 to 194. A zero value on the decibel scale represents the weakest sound audible to humans and sound intensity increases in correspondence with numeric values, the relationship among the values on the decibel scale is not linear but algorithmic. Here is an example of the decibel scale http://www.explainthatstuff.com/soundlevelmeters.html
