It is the responsibility of the captain of the vessel to ensure that it can be detected when sailing in fog- nowadays this is mostly done by GPS and by the use of radio communication, but the skipper of a sailing vessel in foggy conditions should also use a foghorn of some kind, be it a hand-held horn powered by compressed air, or a more sophisticated electrical or pneumatic type that is installed on the vessel itself. There is no set type of audio signal to alert other mariners that a sailing vessel is in the vicinity- Morse Code is no longer used and most modern sailors don't understand it, so it would just be a general foghorn note.
The sound signal that you should hear when a power boat is in the fog is one prolonged blast at intervals of no more than 2 minutes.
One prolonged blast plus two short blasts every two minutes. Explanation: Sound signals let other boaters know where you are located during periods of restricted visibility, such as extreme fog. If you hear the fog signal of a vessel you cannot see, slow to a minimum speed until you are sure there is not a risk of collision. One prolonged blast plus two short blasts at intervals of not more than two minutes is the signal used by sailing vessels.

Electrical to sound.
It is behind the radio. So you will need to take out your center console and radio to get to it. It should be a little black box. If your turn signal still make a clicking sound, you can put your ear near it and hear the clicking sound.
Stay out of the way! One prolonged blast is the whistle signal for a ship leaving a berth or in a blind bend in a channel.
A signal generator produces electrical signals that can be converted into sound waves by speakers or other devices. The generated signal can vary in frequency, amplitude, and shape to create different types of sound waves.
A speaker is a device that converts an electrical signal into a sound wave with an increase in loudness. The electrical signal causes the speaker's diaphragm to vibrate, producing sound waves that we can hear.
