Final answer:
The loudness of a sound is closely associated with the amplitude of the sound wave. There are several ways to make a sound louder, including increasing the amplitude of the sound wave, increasing the intensity of the sound source, and changing the acoustics of the environment.
Step-by-step explanation:
The loudness of a sound is closely associated with the amplitude of the sound wave. Higher amplitudes are associated with louder sounds. Loudness is measured in terms of decibels (dB), a logarithmic unit of sound intensity.
There are several ways to make a sound louder. One way is to increase the amplitude of the sound wave. This can be done by using a larger instrument, such as a bigger drum or a larger speaker, which will produce a sound wave with a greater amplitude and therefore be louder. Another way is to increase the intensity of the sound wave by increasing the energy or power of the sound source, such as by using a more powerful amplifier or increasing the volume on a stereo. Additionally, changing the acoustics of the environment, such as speaking closer to a reflective surface like a wall, can amplify the sound and make it louder.
