How to reduce the volume of the speaker in the phone Xiaomi when talking

The problem of overly loud speaker in Xiaomi, Redmi and POCO smartphones is one of the most common complaints of users. Often the standard volume scale we see on the screen has a minimum threshold, which is still too high for comfortable communication, and this is especially true in quiet rooms when a sharp sound in the ear causes physical discomfort and irritation.

Unlike media regulation, where the slider drops to a barely audible whisper, the conversational profile often ignores the bottom values, which is due to software limitations of the MIUI or HyperOS shell, which are designed to ensure that speech is legible in noisy conditions, but in silence becomes a problem, and fortunately, there are proven methods to circumvent these limitations and customize the sound individually.

In this article, we will discuss all the available methods, from simple switching in the menu to using hidden engineering tools. The most effective and safe method is calibration through the CIT engineering menu, available on all devices of the brand without obtaining root rights.

Standard methods of adjustment during call

The first step to take before implementing complex settings is to check the basic functions of the system. Many users overlook that multimedia volume and call volume are two independent parameters. During an incoming or outgoing call, specific sliders appear on the side of the device that control the earpiece.

Try to make a test call to a voicemail or a friend's number. When you connect, press one of the audio adjustment buttons. You should have a separate slider with the phone handset icon on the screen. Make sure it's twisted to the minimum. Even if the sound is deafening, this confirms the need for deep tuning of the software amplification levels.

Also worth checking is the special features settings. Some versions of MIUI firmware include hearing enhancements for people with hearing impairments that can artificially inflate the output level, and turning off these options sometimes returns a normal, quiet volume.

• 📞 Make a test call and reduce the sound with side buttons to the point during the conversation.
• 🔊 Check if the “Loudness in your pocket” function is enabled in the sound settings.
• 🎧 Make sure that the system does not activate the "Mono-audio" mode, which can add channels and increase the signal level.

It is important to understand that standard methods can only select one of the (pre-installed) levels. If the hardware implementation of the speaker in your Xiaomi model is initially designed for high power, the software slider may not go down low enough.

⚠️ Note: If standard volume reduction does not help, in any case do not seal the speaker hole with tape or tape.This will lead to a deterioration in the quality of voice transmission to the interlocutor and can damage the speaker membrane due to changes in acoustic pressure.

Using an engineering menu to calibrate sound

The most effective way to solve the problem is to access a hidden settings section known as the Engineering Menu or CIT, a tool designed for factory diagnostics but allowing the user to access low-level parameters of the audio codec, which is where you can change the gain (gain) for various use cases.

To enter the menu, you need to open the standard Phone app and enter a special combination of characters. Once you enter the last character, the menu will open automatically. If this does not happen, your shell version may block direct code entry, and then you will need to use third-party call emulator applications such as Engineer Mode MTK (for MediaTek processors) or analogues for Snapdragon.

💡

Before making any changes to the engineering menu, be sure to write down or photograph the original settings, which will allow you to return the settings in case the sound becomes too quiet or distortions occur.

Inside the menu, we're interested in the audio section, which is usually called Audio or Audio Debug, and you'll see a list of modes: Normal Mode (normal mode), Headset Mode (headset mode), Loud Speaker Mode (loud speaker), and we need the first option, Normal Mode, because it's responsible for the behavior of the phone in the ear.

The key is Gain or Digital Gain, which usually ranges from 0 to 150 or from 0 to 6. Decreasing these values directly reduces the amplitude of the signal fed to the speaker. Be careful: too low can make the voice of the interlocutor indistinct.

Configure Speech Enhancement settings

Speech Enhancement is the heart of the audio settings in the engineering menu. It's fine-tuning how the processor handles voice stream before sending it to the speaker. Depending on your device's processor (MediaTek or Qualcomm), the interface may differ, but the logic remains the same.

You need to find a tab or a list labeled Speech or Vol (Volume). Inside you will see volume levels (Level 0, Level 1, etc.) that correspond to the volume slider positions in the system. Level 0 is the minimum volume, Level 6 is the maximum. To reduce the minimum threshold, you need to change the value for Level 0.

There's a Max Vol or Digital Gain, and when you lower it down, you lower the floor volume. For example, if you default to 130, try to reduce it to 100 or 90. After each change, you press Set or OK to apply the settings. The changes come into effect instantly, you don't need to restart.

It is worth noting that in some HyperOS firmware, access to these settings may be limited, in which case the changes may be reset after the reboot. ADB-commands, but for most users, manual settings through the menu are enough.

Disabling the function "Loudness increase"

Xiaomi smartphone owners often encounter an intrusive feature that automatically raises the volume when an incoming call is made if the phone is in a pocket or bag.The algorithm believes the ambient noise is high and compensates for it, but in silence it results in a deafening sound in the first seconds of the conversation.

To disable this feature, go to Settings → Sound and Vibration. Scroll down to Additional Sound Settings (the path may vary depending on the version of MIUI) and find the "Close Up in Your Pocket" or "Pocket mode" switch and deactivate it.

Also, it's worth checking the smart speaker settings. Some models have an Adaptive Volume option that uses a light sensor to detect environmental conditions. If the sensor is contaminated or closed with film, the phone may mistakenly think it's in bright sun and twist the volume to maximum.

• 🔍 Wipe the top of the screen where the proximity and light sensor is located.
• 🚫 Turn off all sound enhancers in Dolby Atmos settings or DTS, if there are.
• 📱 Make sure the case does not cover the bottom hole of the noise reduction microphone, which can knock down algorithms.

Turning off these features puts volume control back in your hands, preventing the sound level from jumping at the start of a call, which is especially important for people with sensitive hearing.

Third-party applications for volume control

If the built-in tools and the engineering menus fail to achieve the desired result, the applications come to the rescue from the Google Play store. There is a category of programs that allow you to create virtual volume sliders, superimposed over the system constraints, they work on the principle of a mixer, reducing the final digital signal.

One popular solution is the Precise Volume app, which allows you to create volume profiles in 1% increments, whereas the standard Android system uses only 15-30 steps. You can create a Quiet Talk profile where the speaker volume is reduced to 5-10% of the maximum, which is physically impossible to do with standard buttons.

Another option is to use global equalizers like Equalizer FX or Poweramp Equalizer, and while their primary function is to correct frequencies, they also have a Pre-amp, which means that by lowering the preamp, you can significantly reduce the overall volume of the output, including the speaker.

When using third-party applications, it is important to consider that they require permanent permissions to access the system and can consume additional battery power, but to solve the volume problem, it is often the only software solution that does not require flashing the device.

Hardware causes and cleaning of speakers

And you can't rule out the physical factor, because over time, the grid of the speaker accumulates dust, earwax and pile from the pockets, and it creates an acoustic plug, and the sound becomes deaf, and you instinctively want to add volume, but sometimes the opposite effect happens: because of the change in resistance, the membrane begins to behave unpredictably, giving sharp peaks at certain frequencies.

Use a soft toothbrush or a special sticky tape (gel cleaner) to clean your teeth. Carefully walk along the speaker grid to remove contaminants. Do not use sharp objects such as needles or pins, as there is a high risk of damaging the protective membrane or pushing dirt deeper into the case.

Also check if the phone is wet. Even if the device has IP68 protection, the leakage is broken over time. The moisture that gets in can cause the speaker to short circuit, leading to wheezing or inadequately high volume. If you suspect moisture, dry the phone in a warm (not hot!) place for 24 hours.

⚠️ Warning: Never attempt to disassemble the Speaker module yourself unless you have experience.In modern Xiaomi smartphones, it is often glued to a frame or integrated into the screen plume. A sloppy autopsy can damage the plume and lose warranty.
