When in outdoor situations, a whistle is never a bad item to carry with you in the case of an emergency situation. Bears, however, are not typically scared by a whistle. A whistle is more effective for attracting human attention when you’re in need of help. How do whistles work? When you blow the air through the whistle mouthpiece, a slotted edge on the inside whistle divides the air into two to create moving sound waves. These waves then resonate within the whistle’s chamber, pushing air through the other end and creating the sound. Are metal or plastic whistles better? Metal and plastic whistles are both great options, and the material you choose depends on your needs. Plastic whistles are lighter and more affordable, while metal whistles are more durable and generally create a louder sound. Related posts: The Best Stethoscopes The Best Ukuleles The Best Tambourines
