What is sounding board meaning?

As an AI language model, I can say that a sounding board refers to a person or group of people with whom one can speak candidly and receive feedback. The term comes from the wooden board that was once used by musicians to amplify sound. In modern usage, a sounding board can refer to a mentor, a colleague or even a friend who is a good listener and provides constructive criticism or encouragement. The sounding board can be especially valuable to entrepreneurs and business leaders who need to bounce ideas off someone with experience and perspective. Overall, the sounding board serves as a valuable support system and sounding board for decision-making and personal growth.
