Waves have a repeating series of crests and troughs. The crests are where a wave's amplitude is at its maximum. Between every two successive crests is a trough, where the wave's amplitude is at its minimum. The distance between two successive crests (or troughs) is the wavelength. The measure of how frequently new crests are formed is the frequency. The speed of a wave is the product of its wavelength and its frequency.
As you know, sound travels in the form of waves with crests and troughs (high and low points). When two waves meet, constructive or deconstructive interference can occur. Loudness increases when waves interfere constructively, in other words when crests combine with crests or when trough combine with troughs to produce an even larger wave amplitude (the height of the resulting wave). Loudness decreases when waves interfere deconstructively, in other words when crests cancel out troughs to produce a smaller wave amplitude.
"higher amplitude"
The amplitude of the wave changes.
The resulting waveform will have the same frequency as both components although the amplitude will be doubled.
When the crest of one wave overlaps the trough of another, this produces destructive interference. If both original waves are equal in amplitude, then nothing will remain. The waves completely cancel out. However, if one waver is larger in amplitude, then there will still be a wave left over after they meet, but it will be smaller. The amplitude of the new wave will be the larger wave amplitude minus the smaller wave amplitude one. The opposite can also occur. If the crests of two waves overlap, then it produces constructive interference (resulting in one larger wave).

The two waves will move through each other unhindered, however at that exact point they will be canceled out and amplitude will be the difference of the amplitudes of the individual waves. If the amplitude of wave a is 10 and the amplitude of wave b is 7, the resulting height will be 10-7=3. If the waves have the same amplitude, the result will be an amplitude of 0.

A bigger amplitude. If the interference is perfectly constructive (same frequencies, in phase), the resulting amplitude will equal the sum of the two wave amplitudes.
ditruptive infreence
Destructive interference affect the amplitude of a wave because two identical waves with similar amplitude and wavelength, arrive in anti phase, leading to a zero displacement.
