音量以分贝作为衡量单位。
这个比值叫做旁瓣电平(以分贝数表示)。
This ratio is called as the side lobe level (expressed in decibels).
以分贝为单位的功率增益等于10乘以以 10为基的功率增益的对数值。
The power gain in decibels is equal to 10 times the logarithm base 10 of the power gain.
以特定频率范围的分贝值表示。
如果耳朵要连续承受声压为85分贝以上的噪音，则必须加以保护，以减低它所承受的声压。
Protection of ear to reduce sound pressure on it is necessary if the ear is to be subjected to noise at a sound pressure level more than 85 decibels continuously.
我以最大的分贝失声尖叫着跑进休息间，并设法告诉母亲刚刚发生的一切。
I screamed as loud as I could and ran into the lounge and tried to tell mum what had happened.
巴斯过滤器是每倍频程滤波器，最大限度地减少低音能量以同样的速度逐步建立一个简单而优雅分贝的喇叭指示能量向更广泛的角度。
The Bass Filter is a simple and graceful 6dB per octave filter that cuts the bass energy progressively at the same rate as the loudspeaker directs energy to a wider angle.
