The sound has really nothing to do with sea level, but changes with temperature alone. The speed of sound goes up when the temperature goes up and goes down when the temperature goes down. The frequency of sound columns, like of woodwinds or of church organs changes with temperature. If the temperature increases, the frequency increases also.
1 dB is defined as an increase of power to [ 100.1 ] of its original value.100.1 is about 1.2589 (rounded)So an increase of 1 dB is an increase in power of about 25.89 percent.A decrease of 1 dB is a change to [ 10-0.1 ] or 0.7943 of the original power, or a decrease of 20.57 percent.
The speed of sound at 12000 meters above sea level is approximately 295 meters per second. Sound travels faster in colder temperatures and lower pressures, which are characteristics of higher altitudes.
That is a missunderstanding. Decibels are never doubled. The ratio or the factor can be doubled.Doubling means the "factor 2". What does doubling of a "sound" mean?Doubling the (sound) intensity is obtained by an increase of the (sound intensity) level of 3 dB.Doubling the sound pressure is obtained by an increase of the (sound pressure) level of 6 dB.Doubling the loudness feeling is obtained by an increase of the (loudness) level of about 10 dB.
decrease because when temperature is low water is present in atmosphere which let sound to go fast
If the pitch of a sound is increased, the frequency of the sound waves also increases. Since the speed of sound remains constant in a given medium, an increase in frequency results in a decrease in wavelength. Thus, a higher pitch corresponds to a shorter wavelength.
Decibels are a logarithmic unit used to measure sound intensity. As sound level increases, the decibel scale also increases to reflect the higher intensity. So, decibels do not decrease when sound level increases; they actually increase to show louder sounds.
An increase in sound intensity is known as a rise or an increase in volume, while a decrease is referred to as a fall or decrease in volume. Sound intensity is measured in decibels (dB), with a higher number indicating a louder sound and a lower number indicating a quieter sound. This rise and fall in sound intensity can affect our perception of sound and its impact on our ears.
As a musician changes from the first to second sound, the wavelength of the sound can increase, decrease, or stay the same depending on factors such as the frequency of the sound, the instrument being used, and the musician's technique. A higher frequency sound will have a shorter wavelength, while a lower frequency sound will have a longer wavelength.
As sound intensity increases, decibels increase exponentially. This means that a small increase in sound intensity can result in a much larger increase in decibel level.

The relationship between sound pressure level and the perception of sound in a dB scale is that as sound pressure level increases, the perception of sound also increases. The dB scale is a logarithmic scale that measures the intensity of sound, with each 10 dB increase representing a tenfold increase in sound intensity. This means that small changes in sound pressure level can result in significant changes in the perception of sound.

That answer is not easy, but ccroll down to related links and look at "Sound level dependence and the corresponding factors". ten
Pressure has a direct relationship with the speed of sound, which in turn affects the frequency of a wave. As pressure increases, the speed of sound increases. This causes the wavelength to decrease, resulting in an increase in frequency. Conversely, a decrease in pressure would lead to a decrease in frequency.
Sound intensity or acoustic intensity is defined as the sound power Pacper unit area A. The usual context is the noise measurement of sound intensity in the air at a listener's location as a sound energy quantity.
The decibel log scale measures sound intensity by comparing the sound pressure level to a reference level. It uses a logarithmic scale to represent the wide range of sound intensities that humans can hear. Each increase of 10 decibels represents a tenfold increase in sound intensity.
