1. It is recommended for indoor large-area places. Indoors, ceiling speakers, ceiling speakers or wall-mounted speakers are generally selected as speakers. For indoor places of 20 to 60 square meters, a 6W speaker or wall-mounted speakers is generally selected. If you want to divide the details, you can choose according to the noise floor of the specific environment. For example, a supermarket can install a ceiling speaker at 40-60 meters; the noise floor of a hotel lobby is 10-20 decibels lower than that of a supermarket, and a 3W ceiling can be installed at 40-60 square meters. A loudspeaker is enough; in places such as a factory workshop, because the noise floor is too large, a sound column is generally chosen as a loudspeaker. For example, a 40-watt sound column can be installed every 25 meters in an 80-decibel workshop.
2. Corridor location suggestions. The noise floor of the place should also be considered here. Like a hospital, a 3W ceiling speaker is installed at 8-12 meters; a ceiling speaker is installed at a noise floor of about 9 meters in the corridor of a hotel or office building; the corridor of a school is generally every 7 meters. Install a 5W ceiling speaker. If you use a sound column, it is recommended to install a 15W sound column every 15 meters.
3. Recommendations for outdoor places. It is recommended to use HUSPA high-power sound column or lawn speaker as speakers, and the layout should be calculated according to the area. If a high-power sound column is used, generally a 30W sound column is installed for 400 square meters, a 40W sound column is installed for 600 square meters, and a HUSPA60W sound column is recommended for 800 square meters.
Green belts in communities, parks, schools and other places are recommended to use grass speakers. Here, HUSPA has many types for customers to choose from, such as stone type, panda type (animal type), tree stump type, road sign type, and the power is also available in different sizes. Parks and residential areas are relatively quiet, and the requirements for sound quality are not too high. Generally, one is installed at about 35 meters. If the budget is not enough, the spacing can be increased. Because the school has a lot of broadcasts and announcements, it is sometimes used for events, so it is recommended to put a speaker about 15 meters away.
