Senders and receivers should recognise and overcome communication barriers.  External barriers are often easier to overcome than internal barriers.  For example, you may be able to move to a quiet location to read a message if noise is a problem.  You may be able to adjust lighting, seating, or room temperature to prevent these physical conditions from being a distraction.

Some internal barriers can be difficult to overcome.  If you are ill, you may need to postpone taking part in the communication until a later time.  If you have trouble focusing on a message because you are sleepy, you might take a break to walk about the room or open a window to get some fresh air.  These actions may help you feel refreshed and ready to read or listen to the message.

When speaking or writing to someone, be aware of how well the person knows the language you are using.  For example, suppose English is your first language and you are writing to someone who first language is Zulu – use plain English in your message.  Avoid using acronyms, information terms or expressions that the reader might not understand.
