There is no best frequency. If you train a dog correctly any frequency the dog can hear will control it. Your voice, whistle, 'silent' whistle. All are acceptable.
Use a variable Frequency Drive. Sold by ABB, Allen-Bradley, and many others.
Frequency controls the color of the light.
In industrial, there is a device called variable frequency drive (allso frequency inverter, ac drive) to control the motor speed by adjusting output frequency.

A (Safe) Alternative to Prevent Your Dog From Barking A dog parent can also try safe ultrasonic bark control. When your dog barks the ultrasonic bark control unit emits a high frequency sound that only your dog can hear. Each dog bark triggers the bark control unit to emit the sound. The dog will stop barking when he/she hears it. Soon the dog will realize that their barking causes the uncomfortable noise and will stop barking. The ultrasonic bark control is not recommended in a house with cats since they are also able to hear the high frequency sound.There are two types of Safe Ultrasonic Bark Controls: Indoor and Outdoor. The Indoor Bark Control unit sits on any flat surface in your house. The Outdoor Bark Control looks like a Birdhouse and can be placed on any outside tree. The device not only looks great for your outdoor decor but an added benefit is controls not only your dog from barking but also your neighbor's barking dog. The Indoor Bark Control unit can be controlled manually or automatically. Manually means you will press the button when you hear your dog bark. Automatic means the device will emit the sound when it picks up the dog bark. The product is manufactured by a reputable company called Petsafe.
The Dog Silencer Pro's sensor is designed to detect just the frequency of the dogs barking. Its very rare for the Dog Silencer to pick up a frequency from the TV.

Radar receivers have to be tuned to the precise frequency of the transmitter, in order to get the best detection and thus the best picture. The transmitter generates microwaves from a device called a magnetron. The exact frequency can vary with age and temperature. To pick up the echo generated from the pulsed microwave, the receiver is able to be tuned, to allow for differences in transmitter frequency. The control on the radar receiver display, called 'tuning', actually alters the receiver frequency, not the transmitter frequency.
Bose speakers are best for frequency response.
The BEST one i can think of is SimsPets3 you can customize and control the dog(cat or person) you make and it's pretty cool. Also a game called Dog's Life where your a smart cracking dog named Jake trying to rescue his lover.
