It isn't louder (loudness has to do with intensity, and a small whistle can't generate that much intensity), it's a higher frequency. In the range that is inaudible to humans.
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.
The 't' is silent.
T and E are the silent letters in "whistle."

A silent whistle would be used to help train your dog to come. Because of the noise the the dogs hear, they will be drawn to you. Then you can say come and give them a treat and they will soon start associating the word come with actually come to you.

To make your dog stop barking when you blow a dog whistle, you can train your dog to associate the sound of the whistle with a command to be quiet. Start by blowing the whistle and immediately giving a verbal command like "quiet" or "stop barking." Reward your dog with treats or praise when they stop barking in response to the whistle. Consistent training and positive reinforcement can help your dog learn to stop barking when they hear the whistle.
Dogs can't whistle... Oh, wait a minute... purchase a "dog whistle" from a pet store, then imitate its' qualities.
