A power boat that runs aground in poor visibility should sound a signal of three distinct blasts on the horn at intervals of one minute. This signal indicates that the vessel is in distress and requires assistance. Additionally, it is advisable for the boat to display the appropriate signals for vessels at anchor to further communicate its situation.
There is no specific sound signal for any vessel aground in clear visibility - this would include at night. By night she would show the requisite lights. In restricted visibility (fog etc.) A vessel aground shall sound: three distinct strokes of a bell, followed by rapid ringing of the bell for 5 seconds followed by three distinct strokes of the bell. If she is over 100 meters in length she should make these signals in the forepart of the vessel A vessel of less than 12 meters in length shall not be obliged to give the above-mentioned signals, but, if she does not, shall make some other efficient sound signal at intervals of not more than 2 minutes. followed immediately by the rapid sounding of a gong for 5 seconds in the after part of the vessel These signals shall be made at intervals not exceeding one minute
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.
Sound amplification is created by increasing the energy of an audio signal to make it louder. This is typically achieved using electronic devices like amplifiers, which receive the audio signal and output a stronger signal with greater power. The amplified signal can then be converted back into sound waves through speakers, resulting in a louder sound.
The signal-to-noise ratio (SNR) is a measurement used in audio engineering and telecommunications to refer to the ratio of the power of a signal (like sound) to the power of background noise. A high SNR indicates a high-quality signal with less interference from noise, while a low SNR indicates a weaker signal that may be harder to distinguish from background noise.
None. A vessel underway under normal conditions does not need to make any sound signal.If the vessel ceases to make way it still does not make a sound signal unless special circumstances apply.

The device that converts sound into an electrical signal is called a microphone. It captures sound waves and converts them into an electrical signal that can be amplified, recorded, or transmitted.
The human voice is an analogue signal because the frequency of the sound varies in the sound waves as well as their amplitude that gives the power. Analog signal is defined as a signal that has a continuously varying amplitude or frequency. Human speech, and everything else a human hear, is in analog form.
