Answer 1

Answer:

Very easy to decipher. Because the words are self-explanatory: pitter-patter is the sound of raindrops. The first line describes a drizzle and the second a torrent of rain. Pitter-patter, pitter-patter, pitter-patter, pitter-patter…..

Answer 2

Reson behind this :

Rain falling on the ocean makes a loud and distinctive sound that can be used to detect and measure rain at sea. Heavy rain can increase noise levels by up to 35 db across a broad range of frequencies (from roughly 1000 Hz to greater than 50,000 Hz).

Raindrops of different sizes produce different sounds. Small raindrops (0.8-1.2 mm) are remarkably loud because they generate bubbles with every splash. They produce sounds between 13–25 kHz. Medium raindrops (1.2-2.0 mm) do not generate bubbles and are therefore surprisingly quiet. Large (2.0-3.5 mm) and very large (>3.5 mm) raindrops trap larger bubbles, which produce sound frequencies as low as 1 kHz.
