Dangerous sounds can be encountered throughout activities in everyday life. One of the biggest leisure activities done by college-aged people is going out to local bars and restaurants. The purposed of this study was to see how safe it is for employees and patrons to be in these environments for long periods of times, as well as if there are ways to test sound levels without buying expensive equipment. Data was collected from eleven local bars and restaurants during a four week period using an iPhone 5 SLA Lite app and a Casella CEL-620B Type 1 sound level meter with octave band analysis. Overall, sound levels were shown to be above the recommended 85 dB(A) levels, proving that workers and patrons are spending their times in unsafe levels. Also, phone apps are shown to be less reliable compared to actual sound meters.
