The audience should not be forced to strain their ears when perceiving the sound sequence. The phonogram should always highlight the main sound in the background of the others, and place the background below the volume level. The main sound should be distinct and easily recognizable. How many great movies and TV shows ruined by not following the rule that you had to send the file to Transcriberry immediately after the filming to get a high-quality transcription of the movie, it is necessary to follow this principle!

Especially in documentaries. It happened when shooting on location, where the wind was blowing and you could hear the extra noise that was unnecessary at the time. It was a time when they worked with imperfect microphones. And the films failed because the key lines of the characters were unintelligible, did not reach the consciousness of the audience. No less of a failure is associated with the directors' desire to make the music, against which the words are heard, louder. The word, if it is present in the frame as a meaningful component, should not drown in the sounds that surround it.

The third principle. Any soft or faint sound should be recorded at a volume within the average level. The main indication of a quiet sound is the nature of its sound. Only a slight decrease in volume with an additional decrease in background level is allowed. A person whispering, for example, should be recorded at a normal volume level by bringing the microphone close to the actor's (documentary character's) mouth or using a special microphone. When we speak in a whisper, the timbre of the voice changes, the nature of the pronunciation, there are additional sounds that are characteristic of this type of speech.

As the professionals say: you have to take the words of the character right out of your mouth. If you only slightly lower the volume level in the final phonogram, the desired effect will be achieved. To achieve a "whispered" text effect by only lowering the volume level of a normally recorded speech will not work - the sound character will give away the unprofessionalism of an amateur with your ears. In the same way other weak sounds are recorded and reproduced: mosquito squeak, bee buzzing, clock ticking, paper rustling, etc. Principle Four.

Any prolonged loud sound is included in the final phonogram at a volume no higher than the upper comfort level of perception, even if the sound comes from an object in the close-up. Try barking over your buddy's ear! After such a joke he will definitely not thank you. If you overdo it, he might even feel a pain in the ear. To prevent such a thing from happening to the audience, a technique has been developed that allows you to convey to their consciousness, the degree of loudness of the sound.
