SoundTrack

Audiences listen to soundtrack through films in some many different ways nowadays due to many things such as mobile streaming, surround sound, pirate films and cinema and there are many more. Obviously the best way to listen to soundtrack effectively will be to see a film in the cinema. Cinema's are set up in such a way sound reaches its audience the way the director intended it to, this because their high quality speakers placed in the right areas help deliver it across clearly and the environment in which a cinema is, the walls a curtain and padded so that sound doesn't echo and bounce around so different sounds are coming from every angle.
After this their is home cinema's which are very good for the surround sound cinema feel to it and have the added base feel to films also adding to the realism but what lacks here is the environment in which a home may be where sound can bounce off of walls, reach all around so it doesn't give that extra feel like a cinema.
There is also mobile streaming which is a brilliant way to watch films on the go but the main issue here is the environment around you, you could be walking down a street or on a train and the noises around you will interfere with what you're listening to therefore disrupting and taking away the effect the director wants you to feel.

Above is a 5 minute battle scene from the movie 300. In the first minute of this clip their is a lot of sound, both diegetic and non-diegetic. Diegetic is the sound the characters in the clip can hear as well as the audience and non-diegetic sound is sound only the audience can hear for example a soundtrack placed in to add feeling.

In the opening seconds of this scene we hear the diegetic sound of small rocks tumbling to the ground, a sound effect like this can be easily made, and this is called Foley effect. It can be created in a sound proof studio to focus on the sound by collecting rocks and record these rocks falling down larger rocks or objects that can create the same sound. These rocks tumbling helps the audience feel like they are their and adds realism to the scene.
Soon after this we get our non-diegetic sound playing over the scene. This is created in a studio using software like Logic to create the music you may want for the soundtrack of the movie. This particular soundtrack is slow with an orchestra type feel to it to add drama to the scene building up, It also add some adrenaline to the scene for whats to come.
As the army runs we hear the grunts of all the soldiers. This can be recorded outside like foley, by getting recording equipment and then gathering a large crowd of people and simply recording the ground cheering out to give it the real effect of there being loads of people at once.
Finally throughout the scene we hear the metal of the armour crashing together. This can be filmed in a studio by getting metal objects and hitting them together to create the metal banging sound, this adds realism to the scene also.
