Sounds can be represented linguistically through words, this resource is known as onomatopoeia. Onomatopoeia is the use of letters to form words in the language itself to imitate certain non-verbal sounds, such as the sounds of animals, natural phenomena, impacts, devices, etc. Therefore, the correct answer is B.
