Typical layout of loudspeakers in a 5.1 home theater loudspeaker system. Block diagram of a 5.1 channel bass management system, with nominal filtering characteristics. There are notation differences between the pre-bass-managed signal and after it has passed through the bass manager. For example, when using 5.1 surround sound: [2] [3]
The sound engineers for Stone Love Movement (a sound system crew), for example, modified folded horn subwoofers they imported from the US to get more of a bass reflex sound that suited local tone preferences for dancehall audiences, as the unmodified folded horn was found to be "too aggressive" sounding and "not deep enough for Jamaican listeners".
Also large bass boosts by sound system EQ can severely reduce the headroom in the sound system itself. Some vendors are currently providing elaborate room tuning equipment which requires precision microphones, extensive data collection, and uses computerised electronic filtering to implement the necessary compensation for the rooms modes.
In digital and analog audio, headroom refers to the amount by which the signal-handling capabilities of an audio system can exceed a designated nominal level. [1] Headroom can be thought of as a safety zone allowing transient audio peaks to exceed the nominal level without damaging the system or the audio signal, e.g., via clipping.
Two-inch port tube installed in the top of a Polk S10 speaker cabinet as part of a DIY audio project. This port is flared. Unlike closed-box loudspeakers, which are nearly airtight, a bass reflex system has an opening called a port or vent cut into the cabinet, generally consisting of a pipe or duct (typically circular or rectangular cross section).
Audio feedback from microphones occurs when a microphone is too near a monitor or main speaker and the sound reinforcement system amplifies itself. Audio feedback through a microphone is almost universally regarded as a negative phenomenon, many electric guitarists use guitar feedback as part of their performance. This type of feedback is ...
In an audio system containing both microphones and loudspeakers, the total amount of gain in the system can exceed 100 dB. This is usually broken up into a number of smaller steps, called gain stages, where the signal is amplified or attenuated as needed before reaching the loudspeaker.
Sound levels as low as 40 dB(A) can generate noise complaints [43] and the lower threshold for noise producing sleep disturbance is 45 dB(A) or lower. [ 44 ] Other factors that affect the annoyance level of sound include beliefs about noise prevention and the importance of the noise source, and annoyance at the cause (i.e., non-noise related ...
