Hair dryers are inherently loud and are used close to the ears, which increases the risk of irritation and long-term hearing damage. Quiet hair dryers are designed to address this by reducing high-frequency tonalities - commonly known as ‘sharpness’ - that the human ear is especially sensitive to. They also feature smoother-sounding propellers to eliminate irregularities in airflow noise, helping the appliance sound consistent and efficient. By reducing these harsh sounds, hair dryers are not only quieter, but provide a more pleasant and relaxed grooming experience.
