🔵 Questão do nível sonoro: ENEM 2023 Matemática (Simplificada) - Logaritmos

ENEM 2023 MATHEMATICS EXAM - Solved Question Booklets: Blue 152 | Pink 155 | Yellow 163 | Gray 177 ➤ Exposure to certain sound levels can cause hearing damage. Therefore, in an industry, preventive measures are adopted according to the machine the employee operates and the sound intensity level N, measured in decibels (dB), to which the worker is exposed, where N = log10 I10 – log10 I010, I is the sound intensity and I0 = 10–12 W/m2. Available at: www.sofisica.com.br. Accessed on: July 8, 2015 (adapted). When the sound is considered low, that is, N = 48 dB or less, preventive measure I should be used. If the sound is moderate, when N is in the range (48 dB, 55 dB), preventive measure II should be used. When the sound is moderately high, which is equivalent to N in the range (55 dB, 80 dB), the preventive measure to be used is III. If N is in the range (80 dB, 115 dB), when the sound is considered high, preventive measure IV should be used. And if the sound is considered very high, with N greater than 115 dB, preventive measure V should be used. A new machine, with I = 8 × 10−8 W/m2, was acquired and will be classified according to the noise level it produces. Consider 0.3 as an approximation for log10 2. The employee who will operate the new machine should adopt the preventive measure. #ENEM #ENEM2023 #mathematics #BasicMathematics #Logarithms 🚀 #NoMoreAlmost!
