Because sound waves are displacements of molecules of the medium they travel through, reducing the amplitude would mean decreasing the displacement the molecules experience as the wave passes through.
Even though sound waves are longitudinal (meaning the displacement is in the direction the wave travels in) and waves in water are transversal (the displacement is perpendicular to the wave's direction), an example can be found in water waves; reducing the amplitude in water waves would reduce the size/height of the waves.
In the case of audible sound waves reducing the amplitude will decrease the volume of the sound.

Increasing the amplitude of a sound wave?
Loudness is the quality of a sound that is the primary psychological correlate of physical strength or amplitude. Loudness is a subjective felt impression and is in some way related to the objective measure of the sound pressure. Neither our ear drums nor the microphone diaphragms can convert acoustic intensity. Therefore only use the sound pressure for measuring. To measure the loudness feeling is a difficult thing. The loudness of 1 sone equals the loudness level of 40 phons (at 1 kHz).
Can sound waves break ice?
Yes, if the sound waves were generated with a frequency that matched the natural frequency of the ice, resonance would occur. If the amplitude i.e. the sound was loud enough, and the frequencies were matched, the ice could vibrate with enough force causing it to shatter.
What units are used to measure sound energy?
The total energy in a specific sound can be measured but that is not the normal way of reporting sound energy.Sound energy is typically characterized as power (energy per unit time) per unit area. The standard units (SI) of sound intensity are W/m2 (watts per square meter).When sound is measured by a sound meter, the result is often reported as a "Sound intensity level" that is expressed in decibels and compared to a defined standard of one picowatt per square meter.There are other measures, such as "sones" which are meant to characterize perceived loudness, but that it not a standard (SI) measure.In standard units then, total energy would be joules, power would be watts, intensity would be watts per square meter.
What is the vertical distance between the highest and lowest points of a wave?
The amplitude of a wave measures the height of a wave, as commonly depicted on a 2-D graph. However, amplitude tends to measure purely the absolute value of the distance from 0 or the baseline. So a wave with a height of 2 would not be said to have an amplitude of 4 due to the height above and below 0, but rather just an amplitude of 2. Hope this helps.
What would happen if the guard cells are closer together?
The stomata would be narrower, thus osmosis would occur less, thus photosynthesis would be less. The stomatal pore will become narrower. Gaseous exchange to and fro stomata will be reduced. This will affect the rate of photosynthesis in green plants.
When a sound wave is diffracted is the amplitude always reduced?
No. A wave travelling in the opposite direction would have its amplitude increased.
What would happen to a sound wave if the energy increased?
It becomes louder. The amplitude of the sound wave increases
Does amplitude mean louder?
No. Amplitude refers to the height of a wave. If the wave is a sound wave a larger amplitude would mean a louder sound.
If the amplitude of a sound wave is increased by a factor of four how does the energy carried by the sound wave in a time interval change?
Well, energy is directly proportional to the square of the amplitude. So if you increase the amplitude of a sound wave by a factor of 4, the resulting energy would be 16 times as large.
What does the amplitude of a wave depend on?
In the case of sound, amplitude is related to volume or loudness.- loud sounds generate waves of larger amplitude and your ear would register sound waves of large amplitude as louder.
What does wave amplitude measure?
Wave amplitude is the strong or weak of the wave, like in sound, it would be the volume.
Does intensity increase with the amplitude of a sound wave?
Yes, but it would be good when you know what amplitude you really mean.
How would you describe amplitude to someone learning about sound?
Imagine a vibrating pendulum moving back and forth. Amplitude in sound is the size of the air particles vibration during the sound.
How does changing the amplitude of a wave impact wave speed?
Amplitude has to do with sound. Vibrating air creates sound using amplitude which is the size of the vibration, and how loud it is. Frequency is the speed of the vibration. The higher the speed, the higher the sound and vice-versa. Amplitude has no effect on wave speed as relates to sound. I believe the same holds for waves of water. Amplitude or size of the wave effects its impact, not its speed.
What is The interaction between waves that meet is?
Interference. This can result in either constructive interference, resulting in increased amplitude, or destructive interference, whereby there would a reduced amplitude.
What does the amplitude look like for a soft sound?
Amplitude is how loud it is. So a soft sound would have a small amplitude. Frequency is the pitch of the sound. High sounds have high frequency. Wavelength is the type of sound. Music wavelengths are in harmony. Changing the wavelength gives us the different words etc that we make.
What are the characteristics of a sound wave that you would interpret as loudness?
Basically, a sound wave is louder if it has a greater amplitude.
