Strictly speaking, noise is merely unwanted sound, irrespective of the loudness.
The 35 dB sound level from an air-conditioner may be noisy, whereas the 100 dB roar alongside the speedway may well be desired (and dangerous to your ears).
Small amplitude sounds are those that have low intensity and are not very loud. These sounds can be quiet or subtle, such as a whisper or rustling leaves. They are in contrast to high amplitude sounds, which are louder and more intense.
Anything loud. (Tunguska, Crakatoa, bombs)
The loudness of a sound is determined by the amplitude of the sound wave, measured in decibels (dB). Soft sounds have low amplitude and low decibel level, while loud sounds have high amplitude and high decibel level.
High sounds are usually heard when you play the keys of a piano that are on your right; they have shorter wavelengths than low sounds. Low sounds are usually heard when the keys on a piano's left end are played; they have long wavelengths. Soft sounds are quiet and can't render your ears deaf. Loud sounds that are over 85 decibels can damage your hearing.
Examples of objects with high amplitude include earthquakes, tidal waves, guitar strings vibrating vigorously, and loud sounds produced by speakers at a high volume. In each case, the amplitude refers to the maximum extent of the wave's oscillation or vibration.

By vibration of vocal chords.. High frequency of vibration/low pitch = sweet sound Low frequency of vibration/high pitch = harsh sound High amplitude = loud sound
The amplitude to a wave is high.

high frequency, high amplitude.
A loud sound.
The two properties are :- Pitch & Amplitude
Amplitude in sound refers to the strength or intensity of a sound wave, which determines how loud the sound is. Higher amplitude waves create louder sounds, while lower amplitude waves create quieter sounds. Amplitude is typically measured in decibels (dB).
When increasing the volume of music played through a music system, you are increasing the amplitude. The amplifier is giving the sound waves more energy, which causes the music to sound louder.
