What is a sounding board?

A sounding board is a person or group of people who provide feedback and advice on a particular topic or project. They are often used to help validate ideas, gain new perspectives, or make decisions. Sounding boards can be composed of peers, mentors, experts in the field, or anyone who has relevant experience or knowledge. The goal is to get unbiased feedback and suggestions from a diverse range of sources to make informed decisions or improve upon certain aspects of a project or idea.
