Most of the audio equipment has been digitized, and one has to admit that the two ends of the tone equation—input and output—are still essentially analog. Just as audio experts began to embrace digital technology, IT engineers began to study acoustic languages. The first obstacle they encountered was often a web conference and discussion system.

Clarity is the key

First of all, the meaning of sound quality is not absolute. It depends on the environment. The sound of "good sound quality" is not the same as the meaning of "good sound quality". The reasons are as follows:

Music is about fidelity. To get good sound quality in music, you need to reproduce the complete frequency range of the instrument. The harmonious blend of basic frequency and overtone frequency produces an extraordinary aesthetic, and the reverberation in the room further enhances this feeling.

On the other hand, the voice is about clarity, which is very different. The ultimate goal of clarity is to be able to easily distinguish what each word is spoken. It seems very simple, right? Actually, the noise-induced interference has a significant impact on our accurate perception of speech.

Have you tried chatting in an old high-class auditorium? Time-lapse reflections make music richer and more solemn, but it is the enemy with the sharpest clarity.

Speech intelligibility is of the utmost importance in corporate, institutional and government environments. You want the CEO's speech to sound good. You want academic reports to be fully understood. Members of Parliament hope that everyone will hear their voice. Factors that may affect audibility during a meeting or meeting need to be mitigated or eliminated.

Everything starts with the microphone

The sound quality of the system is determined by the weakest link, so capturing high quality audio at the source is critical. The microphone is still the starting point for achieving this goal.

The types of microphones that are mainly used in conference rooms or conference rooms are bracket-mounted and wearable. Special types such as surface mount or suspended microphones are not uncommon. Some design elements are common to usage scenarios such as voice and presentation. Most will have a built-in spray hood and shock mount to minimize noise. Size, shape, weight and look and feel are also important design considerations.

Even in the relatively stable case of permanent installation of microphones for talks and conferences, it is difficult to give a versatile choice for choosing the right microphone. The system you want to use—for example, the system that allows the audience to speak, and the system that is appropriate for the lecture (with one major speaker)—will affect to some extent the type of microphone that best fits this task. Although the basic principles are common, different methods of microphones to prevent accidental problems are different.

How to set up and use a microphone during talks and meetings

    Here are some simple setups and tips to share with IT colleagues and speakers before the start of the talks to improve the clarity of the meeting or meeting.

   · The speech should be clear and natural.

   ＆#8226; The microphone is aimed at the mouth and deviates from any other sources of noise.

   · Avoid excessive holding of the microphone, knocking on the table, turning the paper, etc.

Next, let's take a look at the types of microphones you might have installed in your conference or discussion system, as well as some tips for each type of microphone:

00

Handheld microphone

Settings:

1. For a balanced, natural sound, place the microphone 4 to 12 inches in front of your mouth and slightly off the center axis to avoid breathing noise.

2. Too close to a one-way microphone will produce a popping sound due to the proximity effect. This type of excess bass can be adjusted by the equalizer (low frequency attenuation).

3. Talking too loudly to the microphone will produce breathing noise. Use the accessory hood to control the breathing noise of the speaker.

Use:

Hold the barrel only when in use. Do not grab or hold the microphone cover, as this will affect its pointing characteristics.

00

Gooseneck microphone

Settings:

1. Place the microphone 8 to 16 inches in front of the mouth, slightly off the center axis. Just below the mouth to avoid breathing noise.

2. After placing the speaker, do not touch the microphone or gooseneck accessories.

Use:

1. Keep the distance between the microphone and the microphone fixed to ensure the volume is stable.

2. Do not tap the microphone or blow into the microphone.

Lapel microphone

Settings:

1. Place the microphone as close as possible to the mouth, preferably under the neckline.

2. Avoid placing under clothing or other materials that may touch or rub the microphone.

3. Use a windshield, especially a one-way lavalier microphone.

Use:

1. Make sure to "speak to the microphone all the time", please turn around instead of turning your head.

2. Even the slightest noise, the lavalier microphone will be transferred to the sound system. Don't touch the microphone or cable as long as you wear it.

3. Avoid blowing directly into the microphone.

00

Headset microphone

Settings:

1. Do not put the microphone directly in front of your mouth, this will pick up the noise.

2. Place the microphone on the corner of your mouth and do not touch your face.

3. Use a windshield to eliminate breathing noise.

Use:

1. Adjust the headband to ensure that the wear is fixed and comfortable.

2. Do not tap or hold the microphone.

Computers need accurate data to produce reliable results, and the sound system is the same: only the high-quality sound is received to produce the same quality sound. This may be a good start: use your microphone with the right system.
