60 decibels is as loud as a normal conversation between two people sitting at a distance of about one meter (3 ¼ feet). It is the average sound level of a restaurant or an office. 60 decibels is considered a safe sound level for human hearing as it is under the generally accepted limit of 85 dB that is considered dangerous.

Boeing 707 or DC-8 aircraft at one nautical mile (6080 ft) before landing (106 dB); jet flyover at 1000 feet (103 dB); Bell J-2A helicopter at 100 ft (100 dB). 8 times as loud as 70 dB. Serious damage possible in 8 hr exposure.

2024年8月22日 · How Loud Is 60 Decibels? A typical conversation between two people seated at a distance of roughly one meter (3 and a quarter feet apart) is about 60 dB loud. It’s the typical noise level in a cafeteria, restaurant, or office.

2022年9月26日 · A计权 (A-Weighted) 是一种用于音频测量的标准权重曲线，用于反映人耳的响应特性。声压电平源于A计权，用dbA表示，或称为A计权dB电平。A计权是广泛采用的噪声的单值评价指标，可以通过声级计测量得到。

2024年3月11日 · 60 dB is about as loud as a conversation between two people about a table length apart. Generally, an office or restaurant sound is measured at about 60 dB. But if you compare that to a ceiling fan that can measure 60 dB, it is not the same.

60分贝是表示声音大小的一个数值，根据声音声压来分类，目前将声音分为10分贝-100分贝不等，对于60分贝声音来说，属于中间分贝，在城市区域噪声标准中属于噪音范围内，但是具体60分贝声音有多大，我们举例说明：

60分贝等于多少级？ 噪声在0～120dB的范围内分为三级：（1）Ⅰ级（30～59dB）：可以忍受，但已有不舒适感，达到40dB时开始困扰睡眠。 （2）Ⅱ级（60～89dB）：对植物性神经系统的干扰增加，听话困难，

2007年2月5日 · 分贝，分贝是声压级的大小单位（符号：db），声音压力每增加一倍，声压量级增加6分贝。 1分贝是人类耳朵刚刚能听到的声音，20分贝以下的声音，一般来说，我们认为它是安静的，当然，一般来说15分贝以下的我们就可以认为它属于"死寂"的了。

14 小时之前 · The decibel scale is designed to reflect the way humans perceive sound; an increase of 10 dB represents a tenfold increase in intensity and is usually perceived as double the loudness. For example, normal conversation is around 60 dB, while a rock concert can reach levels of 110 dB or more.

2024年11月6日 · Sound levels are most commonly measured in decibels (dB), which range from barely audible to loud enough to cause physical pain. The risk of hearing loss starts at around 70 dB. Exposure to sounds at 85-decibel levels and above damages your hearing. A normal conversation registers at around 60 decibels.
