The troubles faced by tour guides during their tours have slowed down the pace of professional explanations
After working in the audio equipment industry for many years, I have talked with countless front-line tour guides. What they joke about the most is the inconveniences they encounter when leading tours. These seemingly insignificant little troubles not only wear out the patience of the tour guides but also directly lower the professionalism of the explanations, resulting in a discounted tourist experience.
Speaking loudly hurts the throat, and in noisy environments, it's hard to hear clearly
This is definitely the most troublesome thing for tour guides, without a doubt. Especially during peak seasons in scenic spots, when there are many people and loud noises, tour guides have to shout to make the passengers in the back rows hear clearly. After a whole day of this, the throat becomes dry and hoarse, making it difficult to even drink water. In severe cases, they have to rest for several days before they can lead tours again. Even so, during windy days and noisy crowds, there are still tourists who can't hear clearly, frequently interrupting questions, and the smooth flow of the explanation is completely disrupted. The tour guide is tired, and the tourists are not satisfied either.
Multiple teams explaining simultaneously, interference is inevitable
In popular scenic spots and museums, it's common for several tour guides to lead groups at the same time. Traditional audio equipment is prone to malfunction due to signal interference. Tour guides have to switch between different teams, which is not only cumbersome but also time-consuming. This often leads to interrupted explanations and incoherent transitions, disrupting the tour pace, confusing tourists, and causing complaints. It's really frustrating.
Heavy equipment difficult to carry, cumbersome management
Many traditional audio equipment, including transmitters and receivers, are large and heavy. When tour guides lead tours, they have to carry the transmitter and manage dozens of receivers at the same time. After running around all day, their shoulders and backs are sore. What's more troublesome is charging and storage. They have to plug in and charge one by one and sort and categorize them. The whole process is already exhausting enough, and they still have to spend their rest time on the equipment, which really wastes time and affects the next day's tour performance.
Difficult to switch among multiple tour guides, challenging to handle large groups
When dealing with large groups of over a hundred people, often several tour guides need to explain separately and seamlessly. But traditional audio equipment does not support quick switching and is very cumbersome and time-consuming. This often leads to interrupted explanations and incoherent transitions, disrupting the tour pace, causing complaints from tourists, and making the tour guide very passive, with professional quality directly reduced.
