amplifiers
A higher amplitude or greater energy in sound waves makes pitch louder. The intensity or volume of the sound wave determines its loudness.
It's amplification.

bullhorn
pick ups and an amp
you sing through a microphone and it makes the voice louder. the sound of the louder voice comes from the amplifier.
To change the sound, For instance an overdrive pedal boosts the sound making it louder and clearer, where as a distortion pedal makes it louder but less clear.
A sub-woofer.

Resonance enhances sound by amplifying specific frequencies that correspond with the natural frequency of a system. When an external sound wave matches the resonant frequency of an object, it causes the object to vibrate more vigorously, resulting in a louder sound. This amplification effect is what makes resonance contribute to making sound louder.
Sound is determined by the amount of energy the source produces. A louder sound is created by a source that produces more energy, while a quieter sound is produced by a source with less energy. The amplitude or intensity of the sound wave also plays a role in determining the volume of the sound.
The amplitude of a sound wave determines its loudness. A larger amplitude produces a louder sound, while a smaller amplitude produces a softer sound. The distance from the sound source also affects perceived loudness, as sound waves spread out and lose intensity over distance.
