Question

Was the music loud enough to be heard at the starting distance?​

Answer 1

The sound intensity decreases inversely proportional to the squared distance, that is, with 1/r² from the measuring point to the sound source, so that doubling of the distance deceases the sound intensity to a quarter of its initial value.

Answer 2

The sound depth decreases inversely proportional to the squared distance, that is, with 1/r² from the measuring factor to the sound source, in order that doubling of the gap decreases the sound depth to 1 / 4 of its initial value.

Loudness and Intensity:

• Loudness refers to how loud or gentle a valid appears to a listener. The loudness of sound is determined, in turn, via way of means of the depth, or quantity of energy, in sound waves.
• The unit of depth is the decibel (dB). As decibel stages get higher, sound waves have extra depth and sounds are louder.
• For each 10-decibel boom in the depth of sound, loudness is 10 times extra.
• The depth of sound effects from factors: the amplitude of the sound waves and how ways they have got traveled from the source of the sound.

Additionally, it spans the distance from the root to the fifth of the major and is usually not loud enough to be heard as pitches in their own right.
