| 4 | 1 | 2018-04-17 04:02:28 | A | 4 | 2018-04-18 23:12:44 | A Programming Language | APL (A Programming Language) is a general-purpose, third-generation (3GL) programming language that allows certain data manipulations to be expressed with a special non-ASCII set of symbols, resulting in programs that are shorter than would be possible using most other languages. APL's notation allows matrix manipulation as well as recursion functions to be built into simple expressions rather than requiring multiple language statements. APL is more frequently thought of as a language for scientific computation, but it can be used for other purposes as well. Programs can be developed interactively and are usually interpreted rather than compiled. The special symbols require keyboard support and specific editors so that the symbols can be displayed and printed. |

In the A-weighted system, the decibel values of sounds at low frequencies are reduced, compared with unweighted decibels, in which no correction is made for audio frequency. This correction is made because the human ear is less sensitive at low audio frequencies, especially below 1000 Hz, than at high audio frequencies. |
