To make the sound sound loud, press harder down on the key. To make it sound quieter (piano) press lighter down on the key.
Sound can be quieter if it travels a shorter distance, encounters more obstacles or barriers which absorb or dissipate the sound energy, or if the source of the sound is less powerful or further away from the listener. Additionally, using materials that absorb or dampen sound waves can also make the sound quieter.
Mutes change the sound from your instrument, for example making it more lyrical. The "hotel-room" style mutes are used to make the music quieter.
A quieter one.
Increasing the amplitude of a wave will make the sound louder, while decreasing it will make the sound quieter. Amplitude affects the volume of the sound but not its pitch.

Using a mute with a trumpet, contrary to popular belief, does not just make the trumpet quieter. It changes the sound to fit a certain style of music. There are three main mutes which are used frequently, the Straight mute, which is used for classical music, the cup mute which is used for jazz, and also the Harmon mute, which is also used for jazz.
Soft surfaces absorb sound waves rather than reflecting them, which helps to decrease the overall volume of sound. This absorption reduces the reverberation or echoing effect that can amplify and sustain sounds in a space. Soft materials like carpets, curtains, and upholstered furniture are commonly used in buildings to help dampen sound and create a quieter environment.
Because of air damping.
Sound does indeed get quieter through medium. The level of loss depends on the medium that is used, and as the square of the distance from source.
Low sone is quieter than high sone. Sone is a unit that measures the perceived loudness of a sound, so a lower sone rating corresponds to a quieter sound.
When sound waves interfere and result in quieter sound, it is known as destructive interference. This occurs when waves are out of phase and cancel each other out, reducing the overall amplitude of the sound.
