Which tool can be used to overcome training ground noise if the noise cannot be controlled?

Using a microphone and speaker system is an effective solution to overcome training ground noise when it cannot be controlled. This option ensures that the instructor's voice is amplified, making it easier for all students to hear the instructions clearly, regardless of the background noise. This method not only maintains the flow of the training session but also ensures that important safety instructions and teaching points are communicated effectively.

In contrast, cancelling the training session would negate the opportunity for learning and skill development. Providing two-way radios could complicate communication further, as students may struggle with multiple channels of communication amidst noise. Speaking loudly or shouting might lead to vocal strain for the instructor and could diminish the clarity of the message, potentially causing further confusion among the participants. Using a microphone and speaker system directly addresses the issue of noise while facilitating a productive learning environment.
