Loudness. Volume.
As the amplitude of a sound wave decreases, the volume or loudness of the sound also decreases. This is because amplitude is directly related to the intensity of the sound wave, which in turn affects how loud the sound is perceived. So, a lower amplitude results in a quieter sound.
The proper word for strength of a wave is "amplitude." Amplitude refers to the maximum displacement of a wave from its resting position.
The word loudness belongs to psycho acoustics and tells how we feel this sound, that is not measuring the sound like we do with a sound pressure meter. Listening to music means motion to the ear drums. Only sound pressure moves the ear drums. The energy or the sound intensity is much less important here. Sound intensity belongs more to the noise fighters.
The loudness of a sound is directly related to the amplitude of the sound wave. When two sound waves combine through interference, the amplitudes can either reinforce each other (constructive interference) or cancel each other out (destructive interference), affecting the overall loudness of the sound.
The loudness has to do with the sound field quantity called sound pressure or sound pressure level (SPL). The sound intensity or acoustic intensity means the sound energy quantity. Our ears and the microphone diaphragms are moved by the sound pressure variations.

The amplitude to a wave is high.

Amplitude is the usual term, this may be peak too though or peak to mean level.

loudness, number of decibels, magnitude, amplitude, intensity, pitch
Changing the amplitude of a wave will increase or decrease its maximum displacement from equilibrium. This will affect the wave's intensity or energy level, but the frequency and wavelength of the wave will remain the same. In terms of sound waves, changing the amplitude will make the sound louder or softer.
The frequency of a wave refers to how many complete cycles occur in a given unit of time, while the wavelength is the distance between two consecutive points of a wave that are in phase. The amplitude of a wave, on the other hand, measures the maximum displacement of a point on the wave from its rest position.
Loudness is a word from psychoacoustics. It is the quality of a sound that is the primary psychological correlate of physical strength or amplitude. Loudness is a really subjective measure. It is often confused with objective measures of sound pressure or sound intensity. The perception of loudness varies from person to person, therefore it cannot be universally measured using any single metric. Loudness is also affected by parameters other than sound pressure, including frequency and duration. Scroll down to related links and look at "Dependance of sound levels and the corresponding factors - The subjectivly sensed loudness (volume)".
In order to find out the loudness of sound waves, an oscilloscope can be used. Oscilloscopes demonstrate sound wave patterns, but it must be hooked up to a microphone in order for it to be heard.ADDED: It is measured directly and quite accurately by sound-level meters, and these are used by environmental-monitoring specialists etc..You can use an oscilloscope, but not directly. That shows the sound's wave-shape as a voltage analogue, so to calculate the sound level itself from the display on the screen, you also need to know the sensitivity of the microphone and the gain of any amplifier. If you want to determine the sound's full characteristics, replace the oscilloscope by a spectrum-analyser.
