This paper further introduces the Simulink experimental manipulations, such as digital FIR filters' design, stereo channels' wave files creation, etc., in the Appendix. According to the experimental results, this paper concludes that 1) for a conversation in a quiet field, in soft or low noise field, the common DMs achieve comfortable S/Ns: 7 to 33 dB, similar to what the Omni mic does 2) for a conversation in low, competing or strong talking interference fields, the common DMs achieve about 16 dB better S/N than the Omni mic does 3) for a conversation in competing or strong surrounding noise field, the common DMs do not achieve beneficial S/N to understand speech the common DMs' noises are close to the Omni mic noise 4) in various experiments, the balanced DM preserve speech fidelity well as the Omni mic does, while the conventional DM does poorly. As an active listener, you take part in the communication by understanding their message, comprehending the information they present, and responding. focuses on something other than the verbal content of the primary message, you are listening to entertain yourself. Active listening is how you receive verbal information in which you give your complete focus and attention to the speaker. The research methods include analytically deriving sensitivity-gains, statistically calculating the three mics' outputs, experimentally viewing waveforms and spectra, and using large-sample wave files for a high confidence level. Active listening is a critical skill for effective communication. Each type of noises is at 4 or 5 levels, from 30 to 70 dB SPL, at 10 dB step, and each talking interference is at 3 levels: 50, 60 and 70 dB SPL. It may be warmth, brightness, or a shrill harshness that's conveys the emotion of a performance best in a particular type of music. Critical listening is a form of listening that if usually not mentioned, since it involves analysis, critical thinking and judgment. ![]() ![]() ![]() The evaluation focuses on noise outputs, signal-to-noise ratios(S/Ns) and distortions the real-world sounds include male voices, female voices, babble noises, white noises and talking interferences. The critical listening aspect deals with the different types of sounds and the frequencies areas in them that are most important for capturing the intended feeling. Learn the definition of effective listening, and understand the characteristics of effective listening skills. The microphones include a conventional directional microphone(DM), a balanced DM, etc., plus the Omni microphone (mic) as a benchmark. We present extensive experimental data to objectively evaluate the benefits and limitations of common directional microphones in real-world sound fields. In its simplest form, critical listening means paying attention to the details and being aware of how this information makes you feel.
