In decibels, doubling the intensity corresponds to an increase of approximately <strong>3 dB<\/strong>.<\/p>\n\n\n\n<p>So: Total&nbsp;sound&nbsp;level=70&nbsp;dB+10log\u206110(2)\\text{Total sound level} = 70 \\text{ dB} + 10 \\log_{10}(2)<\/p>\n\n\n\n<p>Since 10log\u206110(2)\u22483&nbsp;dB10 \\log_{10}(2) \\approx 3 \\text{ dB}, Total&nbsp;sound&nbsp;level\u224870+3=73&nbsp;dB\\text{Total sound level} \\approx 70 + 3 = 73 \\text{ dB}<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h4 class=\"wp-block-heading\">Step 3: Why Not 140 dB?<\/h4>\n\n\n\n<p>A common misunderstanding is to add 70 + 70 = 140 dB, but the decibel scale is logarithmic, not linear. A doubling of sound energy adds only 3 dB, not 70.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h4 class=\"wp-block-heading\">Additional Notes:<\/h4>\n\n\n\n<ul class=\"wp-block-list\">\n<li>If you had 4 violins, sound level increases by about 6 dB over one violin (because doubling twice: 3 dB + 3 dB = 6 dB).<\/li>\n\n\n\n<li>To increase sound level by 10 dB (which sounds roughly twice as loud to human ears), you need 10 times the original intensity.<\/li>\n\n\n\n<li>The 3 dB rule applies only for sources that are <strong>coherent<\/strong> or independent but identical and uncorrelated sources add power, which leads to a 3 dB increase in sound intensity level.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Summary:<\/h3>\n\n\n\n<p>Two identical violins each producing 70 dB combined create about <strong>73 dB<\/strong> sound level due to the logarithmic nature of the decibel scale.
