Description: "These lightweight earmuffs block out background noise but still allow kids to hear nearby conversations and participate in their surroundings. This could be a useful tool for children with autism, who have anxiety in loud or crowded spaces, or who are overwhelmed by too much noise. Helps muffle sound in for noisy environments like lunchrooms, gymnasiums, or during free play in classrooms. Reduces noise up to 20 decibels. Note: Choking hazard for children under age 3."
