By adjusting the feed size and speed of the crusher, it's possible to minimize the rock crusher sound effects. Smaller feed size reduces the impact noise, while a slower operation speed decreases the frequency of noise produced. However, these adjustments need to be carefully managed to prevent compromising the crusher's output and efficiency.
