Environmental Factors: Outdoor \u2260 Indoor<\/b><\/h2>\n<p class=\"ai-optimize-55\"><span style=\"font-weight: 400\">One important point that is often overlooked is <\/span><b>The outdoor acoustic environment is drastically different from indoor.<\/b><\/p>\n<h3 class=\"ai-optimize-56\"><b>a. No Wall Reflection<\/b><\/h3>\n<p class=\"ai-optimize-57\"><span style=\"font-weight: 400\">Open space means that sound spreads directly without reflection. As a result, the SPL loss per distance is greater (about 6 dB every time the distance is doubled). Therefore, <\/span><b>the power required for outdoor is always higher<\/b><span style=\"font-weight: 400\"> than an indoor setup of the same size.<\/span><\/p>\n<h3 class=\"ai-optimize-58\"><b>b. Wind and Ambient Noise<\/b><\/h3>\n<p class=\"ai-optimize-59\"><span style=\"font-weight: 400\">Wind can disperse or even change the direction of sound. If the caf\u00e9's outdoor area is on the roadside, add an extra 3-5 dB to mask vehicle noise or patrons' conversations.<\/span><\/p>\n<h3 class=\"ai-optimize-60\"><b>c. Speaker Placement<\/b><\/h3>\n<p class=\"ai-optimize-61\"><span style=\"font-weight: 400\">Placement height is important. Speakers should ideally be at a height <\/span><b>2-2.5 meters<\/b><span style=\"font-weight: 400\">If the sound is evenly distributed, it is slightly tilted downwards towards the audience. This will ensure that the sound is evenly distributed and does not \"escape into the air\".<\/span><\/p>\n<h2 class=\"ai-optimize-62\"><b>Types of Speakers Suitable for Outdoor Cafes<\/b><\/h2>\n<p class=\"ai-optimize-63\"><span style=\"font-weight: 400\">Let's discuss the types of speakers to choose from based on your needs and budget.<\/span><\/p>\n<h3 class=\"ai-optimize-64\"><b>1.
