To DB or not to DB .MONO DB Design and Manufacturing. DB BISTRO MODERNE- City Club Hotel.DB is a pure count of unit: dB= 10logX.Sound pressue is often also displayed in dB SPL. Other OIE DB or ODBC data sources. Get ready for the next concert of The dB 's. 如何将dBV或者dBm转换成dB 声级?没有简便的方法。? How to convert dBV or dBm into dB of sound level? Noise levels of 40 to 50 dBA start to interfere with sleep. OSNRint通常以dB 为单位,表示为10log(Rint)。 The OSNRint is usually expressed in dB as 10log(Rint).”. 如果我们没有任何数据的话,我们只要更新模型和再次运行db .create_all()。 If we don't have any data, we can just update the model and run db . create_all() again. 交流减少黑社会(以dB 为单位的主要的键)将是:C,降E,和Gb。 A C diminished triad(In the key of Db Major) would be: C, Eb, and Gb. Replicate-ignore-db =dbname不对这个数据库进行镜像处理。 Replicate-ignore-db = dbname is wrong with the database mirroring.在这种情况下该晶体管增益大约为15dB 左右,Fmin大约为0.7(见图3)。 In this case, the gain of the transistor is about 15 dB or so, Fmin is about 0.7(see Figure 3). 因此,截止频率也称为-3dB 频率,实际上该名称更准确且信息量更大。 Thus, the cutoff frequency is also called the- 3 dB frequency, and in fact this name is more accurate and more informative. 它需要大约5秒才能达到80dB ,约6秒回落50dB 。 It will take approximately 5 seconds to reach 80 dB and around 6 seconds to drop back down to 50 dB . 在一些应用中,如强度调平,传输更重要,可接受~10dB 的对比度。 In some applications such as intensity leveling, transmission is more important and a contrast ratio of~10 dB is acceptable. 此外,在任何区域中的平均声压级(声压级)的变化不能超过正负2dB 。 In addition, the average SPL(sound pressure level) variation within any zone could not vary by more than plus or minus 2 dB . 在BreadStreetKitchen今年早些时候开幕之前,Adonis是db Bistro&OysterBar的调酒师。 Prior to Bread Street Kitchen's opening earlier this year, Adonis was a bartender at db Bistro& Oyster Bar. 一个令人高兴的副作用是这种声音传导也保护听力:相同的感知音量需要3-4dB 的声压。 One happy side-effect is that this type of sound conduction also protects the hearing: the same perceived volume requires 3- 4 dB less sound pressure. 客户端发送或接收数据时,它将选择RSSI为8dB 或超过当前BSSID的RSSI的目标BSSID。 When the client sends or receives data, it picks target BSSIDs whose RSSI is eight dB or greater than the current BSSID's RSSI. 通过在FPGA中进行过采样和数字信号处理,该电路可实现大于125dB 的动态范围,并且仍然非常安静。 By oversampling and digital signal processing in the FPGA, this circuit achieves a dynamic range of greater than 125 dB and is still very quiet. 麦克风/线路卡提供了一系列从0dB 到72dB 的增益设置,以及幻像电源和相位反转。 The mic/line card provides a range of gain settings from 0 dB to 72 dB , together with phantom power and phase reverse. 例如:-58dB传声器的灵敏度一般在―28----―66dB 之间选择,不同的用途就有着不同的灵敏度要求。 For example, the sensitivity of -58db microphone is generally selected between -28-- -66 dB , and different USES have different sensitivity requirements. 为了实现这些非凡的性能优势,OM7的设计具有非常低的输出水平(比典型的动态麦克风低8-10dB )。 In order to achieve these extraordinary performance benefits, the OM7 is designed with an unconventionally low output level(8-10 dB lower than typical dynamic microphones).
