What is the Hollow Sound in Audio?
When it comes to audio recordings, you may come across a common problem known as the “hollow sound.” This issue can make your recordings sound distant, lacking depth, and generally unprofessional. Understanding the cause of this problem is the first step towards addressing it effectively.
The hollow sound in audio recordings typically occurs when there is an imbalance in the frequency response of the recording. It often results in a lack of mid-range frequencies, making the audio sound thin and distant. This can be caused by various factors, including:
- Room acoustics: The design and materials of the room where the recording is made can negatively impact the sound quality. Echoes, reverberations, and other acoustic characteristics can contribute to the hollow sound.
- Microphone placement: Incorrect microphone placement can also lead to a hollow sound. If the microphone is too far away from the source or not properly aligned, it may not capture the full range of frequencies and result in an imbalanced sound.
- Improper EQ settings: Equalization (EQ) is a vital tool for adjusting the frequency response of audio recordings. If the EQ settings are not properly adjusted or optimized, it can result in a hollow sound.
Understanding the Causes of Hollow Sound
As an experienced audio editor, I have encountered many instances where audio recordings have a hollow sound. It’s a common problem that can significantly impact the overall quality of the audio. In this section, I will explain the key causes behind this issue, allowing you to better understand why it occurs and how to address it effectively.
Imbalance in Frequency Response
The primary cause of a hollow sound in audio recordings is an imbalance in the frequency response. This means that there is an inadequate representation of mid-range frequencies, resulting in a lack of depth and warmth in the sound. The frequency response is the way an audio device or a room responds to different frequencies. When it is not properly balanced, certain frequency ranges may be overemphasized or underrepresented. This imbalance can create a hollow or thin sound.
Room Acoustics
One major factor that contributes to a hollow sound is the acoustics of the recording space. Suppose you’re recording in a room with hard, reflective surfaces like tiles or glass. In that case, these surfaces can cause sound reflections that interfere with the audio capture, leading to a hollow sound. Similarly, if you’re working in a room with poor sound insulation, external noises can seep in and affect the overall quality of the recording.
Microphone Placement
The placement of the microphone during recording plays a crucial role in achieving the desired sound quality. If the microphone is too far away from the sound source, it may capture more ambient and reflected sound, contributing to a hollow sound. On the other hand, if the microphone is too close or pointed directly at a sound source, it may result in an overly boomy or unnatural sound.
Improper EQ Settings
Another factor that can contribute to a hollow sound is improper EQ (equalization) settings. EQ allows you to boost or cut specific frequencies in the audio signal to achieve the desired tonal balance. If the EQ settings are not properly adjusted, particularly in the mid-range frequencies, it can lead to a hollow sound.
Understanding the causes of a hollow sound in audio recordings is the first step towards effectively addressing the issue. By considering factors such as frequency response imbalance, room acoustics, microphone placement, and EQ settings, you’ll be better equipped to take corrective measures and achieve a cleaner and more balanced audio output.

Remember, the key to effectively removing the hollow sound from your audio lies in understanding the causes behind it. By preparing your audio editing workspace in the right way, you’ll be well-equipped to tackle this issue head-on.
Removing Hollow Sound with EQ Effect in Audacity
Now that we have prepared our audio editing workspace in Audacity, let’s dive into removing the hollow sound using the EQ effect. The EQ effect allows us to adjust the frequency response of our audio, helping to restore balance and eliminate the hollow quality.
To begin, select the portion of the audio that exhibits the hollow sound. It’s important to isolate the affected areas to avoid modifying other parts of the audio that sound fine. You can do this by clicking and dragging your cursor over the specific region, or by using the selection tool to create a precise selection.
Once you have the section selected, go to the “Effect” menu at the top of the Audacity interface and choose “Equalization.” This will open the EQ effect window, where you can make the necessary adjustments.
In the EQ effect window, you’ll see a graph representing the frequency spectrum of your audio. The horizontal axis represents the frequency range, from low frequencies on the left to high frequencies on the right. The vertical axis represents the intensity or gain of the frequencies.
To remove the hollow sound, we need to identify the frequency range that is causing the issue. This can be a bit subjective, as it depends on the specific characteristics of the audio. However, a common range to focus on is the mid-range frequencies, typically around 500 Hz to 2 kHz.
Using your mouse, click and drag on the graph to create a curve that reduces the gain in the selected frequency range. Experiment with different shapes and slopes until you find the curve that best addresses the hollow sound.
Remember, moderation is key. Avoid excessive reductions in gain as it may result in an unnatural or thin sound. Make subtle adjustments until the hollow sound is significantly diminished but still retains a natural and balanced character.
Once you’re satisfied with the adjustments, click the “OK” button to apply the EQ effect to the selected portion of the audio. You can listen back to the modified section to ensure the hollow sound has been effectively eliminated.
Note: It’s important to listen to your audio on multiple playback devices, such as speakers and headphones, to ensure the changes made with the EQ effect translate well across different systems.
Removing hollow sound using the EQ effect in Audacity requires some experimentation and a trained ear. With practice, you’ll become more proficient at identifying the problem frequencies and applying the necessary adjustments to achieve a polished and professional sound.
