One issue that could occur would be the use of the radio mics and not pulling back enough on the down stage monitors when they sing a few of the numbers. 

the black drapes are positioned at the side so noise will be absorbed twice as fast than without them, also with platforms the sound has more deflection time to work with.

Another major issue would be the db level for the performers, technicians and the audience members as the amount of noise over a certain amount of time just gives wear and tear on your ear drums and the level being high constantly can affect your hearing. 

The way in which we hear sound is effected by the way in which a space has been built. The auditorium at the Miskin Theatre is a poor place to set up sound.

The first reason why the auditorium is a poor set up for sound is because it is make of reflective materials. These reflective materials are the shutter for the dock at the back off the space, the bricks that the building is made of and the paint which is over them. These surfaces will effect the acoustics in the room as the sound waves will reflect off the wall and bounce around the space really fast. When the reflect of the wall the waves will collide with each other which in turn will cause the the frequency of the waves to get higher therefore making the sound appear horrible. A way to improve this problem would be to hang blacks around the outside of the auditorium as this will help to absorb some of the sound particles and therefore stop them from colliding with each other.

Another reason why the space is a poor place to set up sound is the fact that the windows to the control room are angled. This again will effect the way in which the sound particles will travel around teh room because firstly the windows are made of a reflective material which will cause the sound particles to bounce off the windows and speed them up and secondly because of the angle that both the windows are at will cause the sound particles to bounce of the windows and travel towards the floor of the space. In order to improve this problem I would suggest either changing the angle of the windows to stop the sound particles being sent to the floor or getting rid of the windows all together as this will stop the particles being sent to the floor of the space and also eliminate the problem of the particles being speed up when they reflect of the windows surface.

The shape of the space is another problem that makes the room a poor place to set up sound. This is because the room is rectangular in shape and therefore will cause the the sound to be constantly bounced around the space at different angles. To improve this problem I would suggest that we knock down the back wall of the the space and make it curved as a curved back wall will help to more evenly spread the sound particles around the room.  

Another problem that will effect the acoustics in the room is the set for the shows that are put in the space. For example if the set was to be made out of metal this would be a problem as it would cause reverberation and again cause the sound particles to be bounced continuously at high speeds around the room and cause them to collide. Also the way at which the set is place will also cause as problem as the sound particles will reverb of the different parts of the set and cause them to be bounced around the room randomly. A way to ensure that this problem does not happen is to have constant discussions with the set designers about how best to lay out the set with regards as to were are speakers are laid out in the space. We can also discuss with the set designer the materials in which the set is going to be made of and make suggestions of alternative materials that can be used. 

The final problem that are space has is feedback. Feedback occurs when the sound that is being sent through the speakers is picked up by the microphones and is then amplified through the F.O.H. P.A., which causes a horrible howling sound. This occurs a lot in our space because on most shows we have are speaker stacks at the front of the stage on both stage right and stage left. This means that when actors with microphones enter the space through the voms they will have to pass the stacks causing the feedback. There are a number of ways in which we can prevent this problem from occurring, the first would be to find a better place to possition are stacks however this is not possible as we have limited space in the auditorium, the second would be to find a new way for the actors to enter the stage so that they don’t walk pass the stacks and the final option would be to Equalize (EQ) the space. EQ is were you level out the frequency’s in a sound system to remove any peaks on the sound wave and help minimize the howling sound created by feedback. EQ will help in minimizing feedback but it will not full prevent it from occurring. 

As well as having acoustic issues the Miskin Theatre also has other issues. The main issue with are theatre is the placement of the voms. The voms are placed on both sides of the auditorium and that is how the audience enter the venue. This means that they have to physically walk on the stage to gain access to the seating bank. For sound Thai is a major issue because we may have speaker stacks on stage right and left which have to powered from under the seating bank. This means that we are running cables across the stage and they are a trip hazard for the audience that are entering. To stop the trip hazard from occur in we would have to tape down the cables to prevent audience members tripping and hurting themselves.

Venue Issues for a selected performance

One of the selected performance I will be looking at is the Christmas show, the venue issues for this performance could range from health and safety to acoustic properties. Looking at acoustic properties for the venue of the show the room is not the best shape for a theater as the room is not very wide so this has the effect of the sound being squeezed through a long corridor. One way round this issue of bad acoustic properties is to hang a boarder round the front of the stage and adding foam blocks to the set this absorbs the sound. It would also be good to hang blacks but for this particular show this was not applicable although there was a back curtain and drape. Another venue issue was the audience had to step on/over wires connecting to the speakers and other equipment in the wings. This might have been done due to the venue not being able to fly them due to other equipment in the rigg.

Other venues have different problems, for example a charity theater group I work for their rood is metal so when it rains during the performance you get a horrible noise of rain hitting and bouncing off of the roof. Also some of the floor boards creek again this is a venue issue due to people moving backstage being heard. Also the speakers are not placed in the right position so the first row of audience don't hear them from the speakers but out of the person who is speaking then they hear it through the speaker behind them so it then sounds like an echo or repeated.
