The need for power escalates very quickly as you approach “lifelike” or “theater” levels of around 100-104 dB. Likewise, an average loud listening level of, say, 91 dB punctuated by a sudden peak of 10-20 dB will make a huge instantaneous demand on your amplifier. This is where y...
With the new performance profile, functionality HammerDB enables you to group related TPROC-C jobs under an ID and use it to compare performance across benchmarks at different levels of utilisation and different configurations. The profile ID chart will show performance for each individual profile....

The Decibel represents a logarithmic relationship between two power levels. Derived from the Bel (in honor of Alexander Graham Bell) – the Decibel corresponds to 1/10 of a Bel . The unit – one Bel at its origin – represents the power ratio of 10 to 1 between the intensity (power) of...
