The decibel originates from methods used to quantify signal loss in telegraph and telephone circuits. Until the mid-1920s, the unit for loss was miles of standard cable (MSC). 1 MSC corresponded to the loss of power over one mile (approximately 1.6 km) of standard telephone cable at a frequency of 5000 radians per second (795.8 Hz), and matched closely the smallest attenuation detectable to a ...
Such a difference can exceed 100 dB which represents a factor of 100,000 in amplitude and a factor 10,000,000,000 in power. [4] [5] The dynamic range of human hearing is roughly 140 dB, [6] [7] varying with frequency, [8] from the threshold of hearing (around −9 dB SPL [8] [9] [10] at 3 kHz) to the threshold of pain (from 120 to 140 dB SPL ...
For this, the Mark 120 is often acclaimed as milestone in locomotive technology. They were based on experiments made in the 1970s with diesel-electric test platforms (Mark DE 2500/ DB Mark 202). In Norway, a new four-axle Locomotive, Mark El-17, was launched during 1983 with top speeds up to 93 miles per hour (150 km/h).
While 1 atm (194 dB peak or 191 dB SPL) [11] [12] is the largest pressure variation an undistorted sound wave can have in Earth's atmosphere (i. e., if the thermodynamic properties of the air are disregarded; in reality, the sound waves become progressively non-linear starting over 150 dB), larger sound waves can be present in other atmospheres ...
Decibels relative to full scale (dBFS or dB FS) is a unit of measurement for amplitude levels in digital systems, such as pulse-code modulation (PCM), which have a defined maximum peak level. The unit is similar to the units dBov and decibels relative to overload (dBO). [1] The level of 0 dBFS is assigned to the maximum possible digital level. [2]

dBm or dB mW (decibel-milliwatts) is a unit of power level expressed using a logarithmic decibel (dB) scale respective to one milliwatt (mW). It is commonly used by radio, microwave and fiber-optical communication technicians & engineers to measure the power of system transmissions on a log scale , which can express both very large and very ...
In November 1994, Deutsche Bahn chose AEG to supply DB's freight business area DB Cargo (today DB Schenker Rail) with eighty locomotives for medium-weight freight trains, the DBAG Class 145. [3] The original Class 145 design was a cheaper derivative of the 12X, leaving away components for higher speeds, including hollow-shaft drives, which were ...
