As much as there are barriers, they can easily be prevented with some common sense:
Preventing background noise – Background noise is something you can’t really stop but you can attempt to minimise it. If you own an office building, it is most likely it will be next to the main road, where you’ll hears cars and people passing by and that can be a major barrier for your performance. What you could do is install soundproof windows, which prevents the sound from travelling through the window, resulting to a quiet office room and a greater chance of your performance at work improving. However this can be expensive and you will need an adequate budget in your company if you
plan to do this.
Preventing general distractions – As I explained in P3, distractions are similar to background noises but can occur anywhere and from anyone. Some examples I used in P3 is that a phone may ring or someone coming in late. The preventions are simple, before you start your presentation should inform the audience to either turn off their phones or at least put it on silent mode, that way you won’t hear any ringing and no random calls will occur. People coming late (especially in the world of work) isn’t acceptable unless it’s a justified reason. Before the day of the presentation, alert your audience to come 5 or 10 minutes prior to the presentation, that way you won’t have anyone interrupting by their late presence.
Lack of concentration – Lack of concentration is all dependable on you. You know and control yourself so you need to make sure you are concentrating on what you’re showing to the audience. One of the factors for a lack of concentration could be due to tiredness and being tired at work or it could be due to little sleep or an inadequate amount of energy from your breakfast. Make sure to go to bed earlier than usual and have a breakfast with slow releasing energy so you can last longer during the day. There are many other factors to lack of concentration but the factor I’ve just stated is a common reason.
