问题      The listener has a given amount of energy to expend in completing the communication process. Any distraction that demands part of that energy will diminish the probability that communication will take place. One of the easiest distractions to eliminate is the too soft voice. You Will find it necessary to adjust your voice level to accommodate the size of the room, the number of people in the audience, the furnishings, and the ambient noise level.
     The desired level is one that seems slightly greater than that normally heard in conversation. If the room is large and filled with people, you will have to put an appropriate amount of power in your voice to be easily heard. In some cases, you may require electronic amplification, which will usually enable you to speak in an ordinary conversational tone.
     Furnishings such as heavy carpets and drapes absorb a good deal of sound, thereby creating a deadening effect on the speaker’s voice. You should be able to judge the effects of the furnishings after speaking the first few sentences. You can then modify your voice level as necessary to account for any sound-absorbing material.
