The term 'FAN NOISES' can be broken down into two crossword solutions: YELLS (5 letters) and RAHS (4 letters). Yells are loud, high-pitched shouts that are often used to express excitement or enthusiasm. They are commonly heard at sporting events, concerts, and other large gatherings. RAHS, on the other hand, are shorter, lower-pitched sounds that are usually used to show approval or agreement. They are often heard in response to a speaker's words or a performer's performance. Both yells and rahs are common fan noises that are used to show support and enthusiasm.
