Ldn/CNEL for the proposed industrial/business <br /> park.A 12-foot sound wall would also reduce <br /> o freeway noise exposure at the nearest proposed <br /> o residences to 61.2 dBA Ld./CNEL,not accounting <br /> for additional attenuation provided by the <br /> n intervening presence of the industriallbusiness <br /> v <br /> n park. <br /> m <br /> 0 <br /> 0 <br /> v <br /> o m <br /> n p <br /> 3 :* <br />
