Sort of. Volume and frequency are independent.
Volume is amplitude. Think of a sine wave here with peaks and valleys. As the tops and bottoms get higher and lower, the volume increases. Or vice-versa. Increasing volume will cause the mountains to be higher and valleys to be lower.
Frequency, like when a man is talking it's low and a woman high, is represented by how close those mountains and valleys are from each other. So if they go up and down many times (looking at it left to right), then the frequency is higher. A really deep male singer will have those peaks and valleys much more spread apart.
Using a digital oscilloscope which easily measures wave patterns, electronics and computers can be diagnosed for proper operation.
