Sounds in Doc Martin clip

There is a difference within sound, being diegetic and non diegetic.

Diegetic: A sound that occurs naturally on or off screen.

Non Diegetic: A sound that doesnt naturally occur. This can be things such as mood music, a narrator or sound effects.

Diegetic
Firstly the phone rings at the beginning of the beginning of the clip, I believe they did this not only because it happened in the clip but I believe they did this action to add more hysteria to the clip. When the sink breaks in also makes a diegetic sound, this exaggerates the fact that the sink has broke and makes it very evident to the audience. The dog barks, and firstly we cannot see him on screen but as the scene continues the dog walks in whilst barking, this makes the dogs entry a smooth transition as we know he is there firstly but cannot see him until he walks in. The hoover in the police station also demonstrates a smooth transition as again we hear it before we see it and then when we do see it, it is expected. Lastly, we hear the woman in the school/church cutting the paper, thus just adds to the scene by telling us what she is doing before seeing Doc Martin.

Non Diegetic
The first sound we hear within the clip is a non diegetic sound, it is when Doc Martin first walks in. I believe they did this because it was the beginning of the moment and just illustrates that you have not missed anything within that scene. When walking into the village non diegetic sound is used again, the sound is upbeat an I believe it is used for ironic, comedic purposes as the music is the complete opposite  to the mood of Doc Martin who is annoyed at the state of his surgery and the fact he has to walk to a village to drop a dog off. When Doc Martin see's the dog before handing it in, tense music is played, this is used so we can assume that something bad will happen to the dog, which we are soon assured by, because he hands the dog into the police. Tense music is played again when Doc's eyes meet with the woman in the school/church, this gives us the idea that there is possibly a tense past, I would class this as mood music as the sound reflects the mood, tension.

There are now 2 more differences within sounds I have been introduced to, synchronous and asynchronous.

Synchronous: When a sound occurs from what is on screen.

Asynchronous: When a sound occurs off screen.

Synchronous
The sink demonstrates the first synchronous sound, we both hear the water spurting out but also see the water coming out. This is both visual and audio working together. We also see the dog when it barks, not firstly which some would say could make it asynchronous, but as it does actually come on screen (in a smooth transition), it makes it synchronous.

Asynchronous
The seagulls are not seen on screen but as we can hear them this sets the scene and lets the audience know they are by the sea. We can also hear the sea very vaguely but again cant see it, this is just the makers way of setting the scene. Lastly we hear phones ringing but do not see them, this is just for effect as it is a natural thing you hear when you are out.
