Những thuật ngữ trong lĩnh vực Audio - Phan Nguyễn Audio

Each specialty has its own terminology. In the audio field, too. Therefore, when you enter the field of sound, you also need to equip yourself with some knowledge and our terminology. Some common terms often appear in products or advertising. you need to understand them to be able to assess the most intuitive of their equipment to be purchased.

Âm thanh

Power (Capacity): The intensity of sound reproduction of a pair of speakers.

Impedance (Impedance): The total amount of countervailing (resistance, capacitance, inductance) on his way to AC. Impedance equal (ohm) and change at different frequency levels.

Watt (power measuring unit): Number Watt larger the capacity of the stronger, but how loud speaker depends on the sensitivity of the speakers, listening room size.

Decibel (dB) is a measure of sound intensity. Each dB is the smallest change in sound intensity, can identify by ear.

Phase (Phase): in the field of audio, phase refers to the relationship in time between two or more waves. For two speakers in the same operating system synchronization is particularly important. That means all the speakers in the speaker system to move out on simultaneously. If the phenomenon of phase speakers will cause a shortage of bass or break stereo imaging.

Audio frequency (audio frequency): Range hear sounds that the human ear, typically between 20Hz and 20kHz.

Frequency Response (Frequency Range): The range balanced sound across the entire audio spectrum is reproduced by the audio device that the human ear can hear at the same volume level, often from 20Hz to 20,000.

Filter (Filter): As circuits or mechanical parts to remove or diminish the energy at some certain frequencies while allowing other frequencies pass through.

Crossover (frequency component) is the passive parts (in one cabinet) or actively (in the treatment) divides specific frequency bands to each speaker separately the system’s speakers. Without crossover, each speaker driver will bear the entire band through it.

Crossover Frequency (cutoff frequency): The frequency that the crossover of the speaker system choose to include audio signals to each speaker children.

Crossover Slope (Slope frequency): On the point of the attenuator when speakers must demonstrate unwanted frequencies, measured in dB / oct. The index is higher the larger the slope, will shrink the area in which, sounds transferred from other speakers to speakers.
