Ultrasonic anemometers are now being used in the field.
An ultrasonic nebulizer is akin to a compression machine and is used in the medical field. It is mainly neccessary for the administration of tombramycin for the treatment of people with Cystic Fibrosis. An individual would be assigned to a machine of this nature when a standard nebulizer has failed to keep the patient out of the emergency room and when as stronger and more intense course of treatment is required.
There is some info at http://www.keyence.com/products/sensors/ultrasonic/ultrasonic.php. They are a manufaturer of them.
Ultrasonic sensores are also known as tranceivers. They are usually used to measure wind speed and direction.
An ultrasonic thickness gauge is required for measuring the thickness of different types of materials. The best ultrasonic thickness gauge you can buy is the Defelsko Corporation Ultrasonic Thickness gauge.
Higher frequencies, typically above 20 MHz, would result in the greatest ultrasonic attenuation losses in materials due to increased scattering and absorption.
Ultrasonic waves can be traced using ultrasonic sensors that emit the waves and then detect their reflections. These sensors send out high-frequency sound waves that bounce off objects and return to the sensor, allowing for measurement of distance, presence, or motion based on the time it takes for the waves to return. By analyzing the wave reflections, it is possible to trace the path and interactions of ultrasonic waves.

Ultrasonic. The opposite would be infrasonic.
We can use ultrasonic planes. They can travel with that speed.
because speakers doesn't create ultrasonic waves, they create sound waves
Ultrasonic thickness gauges can be found at any Grainger like store the reason you would need this type of gauge is if you are measuring coating or linings . The model type that would be best for you would need to be determined by the type of material you are working with.
