1. A noise-reduced nasal respiratory device comprising:
- a noise-reduced airflow resistor comprising a flap valve, wherein the noise-reduced airflow resistor is configured to inhibit exhalation more than inhalation and to inhibit oscillation of a free edge of the flap valve during inhalation when the flow rate is between about 20 and 750 ml/sec; and
a holdfast configured to secure the noise-reduced nasal respiratory device in communication with the subject'"'"'s nasal cavity.

Abstract
Described herein are nose-reduced nasal devices configured to reduce or eliminate the unwanted noises associated with use of a nasal device. These noise-reduced nasal devices include a flap-valve airflow resistor and a noise-reduction feature that is a noise-reduction element, a noise-reduction flap valve, or both. The noise-reduction feature typically prevents the flap valve from oscillating or vibrating and producing an audible sound during use, particularly during inhalation through the device. The method and devices described herein may prevent the flap, and particularly the edge region of the flap face or tip of the flap, from oscillating during inhalation.
