Final answer:
The most crucial difference between voiceless and voiced plosives is voicing.
Step-by-step explanation:
The most important difference between initial voiceless and voiced plosives is b. Voicing. Voiced plosives, such as b, d, and g, are produced with the vibration of the vocal cords, whereas voiceless plosives, like p, t, and k, are produced without this vocal cord vibration.
In relation to the other question, the term used to describe the loudness of sound is b. intensity level or decibel. This is a measure of the power of the sound pressure and can be quantified in units called decibels.
When speaking about the physical properties of sound waves, the GRASP CHECK question would be answered by a. amplitude of the wave. The amplitude of a sound wave increases with the loudness of the sound. Hence, when you speak more loudly, the amplitude of the sound waves produced is greater than when you speak softly.
