The sound waves produced by a whistle are at a higher frequency than that of a beaten drum, causing the sound registered by human ears to be at a "higher pitch". Dog whistles can only be heard by dogs because the sound waves produced are at such a high frequency, human ears cannot detect them.

Whistle-blowing is when an employee at a company, knows that the company as a whole, or individual people who work for the company, are committing serious crimes and tells the press about it. It is important, because the people have a right to know if a company, or people who work for the company, are committing serious crimes against the average person. A recent example of whistle-blowing occurred when it was revealed that Toyota knew that some of their cars had defective brakes and did nothing to correct the problem, or when it was revealed that BP knew some of their oil rigs were not safe and could have a serious accident and BP did nothing to prevent an accident. Whistle-blowing gets its name from referees that sees something wrong during a game and blow a whistle to stop the game.
When the sound on a tin whistle is low it means either the mouthpiece needs a tighten or your not blowing hard enough. P.S. Don't blow too hard or might just blow the ear off your listeners!!!!
A slide whistle is musical wind instrument containing either a metal or plastic reed inside with a plug at the end. As the reed moves up, along with someone blowing into it, the higher the note will be. If it moves down the lower the note will be this is because of the compression of the plug causing low space to create higher frequencies and more space to create low frequencies.
