Does My Ultrasonic Humidifier Hurt My Dog’s Ears?

No, Your Ultrasonic Humidifier Doesn’t Hurt Your Dog’s Ears

The mechanism in an ultrasonic humidifier has a frequency much too high for dogs to hear. Ultrasonic humidifiers use frequencies ranging from approximately 1,600,000 Hz to 3,000,000 Hz. Dogs can hear up to 45,000 Hz. The sound produced by this very high-frequency device is profoundly out of hearing range for both dogs and humans.

Although sounds outside our hearing range can in some cases damage humans’ ears and possibly dogs’, I’ve seen this documented only for extremely low-frequency sounds (Kugler et al., 2014), not high.

When a Dog Suffers a Trauma

The scene is the back interior of a car. There is a bowl of cat food in the foreground. In the back is a dog crate with a distressed brown dog looking away.

Here’s a photo that breaks my heart. Clara the bold, refusing to leave her car crate, even to eat some cat food.

This is what happened.

Early in December, I took Lewis and Clara to the house my sister is going to move into so they could mess around while I cleaned house. It was raining and dreary. There were leaves layered on the lawn and on the steep driveway.
