When the tour guide leads the group to explain, will the explanation content be difficult to convey clearly, and it is easy to be disturbed by the surrounding environment factors, and the voice will be overwhelmed after a long explanation. This is the disadvantage of using traditional public address equipment. The emergence of the audio tour guide has changed this, it makes the explanation no longer just shouting. The audio tour guide can make the tour guide speak clearly and make it easier for the tour guide to explain. These are all derived from the advantages of the audio tour guide, because it has the function of one-to-many explanation, so it can meet the needs of the tour guide to explain clearly and effortlessly when receiving a multi-person team, and also allows the tourists in the team to clearly hear the explanation. Since the audio tour guide conveys the audio content through the audio transmission channel, it will not cause noise like the previously used public address equipment.
The audio tour guide is composed of a transmitter and a receiver, the transmitter is used by the tour guide, while the receiver is worn by the visiting group tourists to listen to the tour guide's explanation. When using the receiver to listen, the team can adjust the listening volume according to their own listening habits, because when using traditional amplified explanation equipment, if tourists get too close, the volume will be too loud, and it is no easy to hear the explanation content when you are far away. The emergence of audio tour guide has improved many disadvantages of traditional public address equipment, and has also achieved effects that traditional equipment cannot achieve, these are the advantages of using audio tour guide. The audio tour guide is now a common explanation device in scenic spots and museums. It not only improves the reception quality, but also eases the tour guide's explanation work.
