Soundbars have become increasingly popular over the past few years, especially among those who are looking for a simple and easy way to enhance the audio quality of their home entertainment setup. A soundbar is a speaker system that is designed to provide better audio quality than the built-in speakers found in most televisions.
However, not all soundbars are created equal, and it’s important to consider sound quality metrics and standards when shopping for a soundbar.
Now that we’ve covered the various metrics used to measure sound quality, let’s discuss
Why sound quality metrics and standards are so important?
First and foremost, having a good understanding of these metrics can help you make an informed decision when shopping for a soundbar. By knowing what each of these metrics means, you’ll be able to compare different soundbars and choose the one that best fits your needs and preferences.
Additionally, understanding these metrics can help you optimize the sound quality of your soundbar. For example, if you know that your soundbar has a frequency response that doesn’t quite reach the lowest frequencies, you may want to consider adding a subwoofer to your setup. Or, if you know that your soundbar has a high level of harmonic distortion, you may want to adjust your EQ settings to minimize this distortion.
Sound Quality Metrics
Now that we’ve discussed the importance of sound quality metrics and standards, let’s take a closer look at some of the most common metrics used to measure sound quality in soundbars.
Frequency response:
Frequency response is one of the most important metrics for measuring the overall sound quality of a soundbar. It refers to the range of frequencies that a soundbar is capable of producing. The frequency response is usually represented graphically as a curve that shows the sound pressure level (SPL) of the soundbar at different frequencies.
Ideally, a soundbar should have a flat frequency response curve, meaning that it produces the same level of sound at all frequencies. However, this is often not the case, and many soundbars have a curve that is shaped like a smile, with boosted bass and treble frequencies.
Impedance:
Impedance refers to the resistance that a soundbar offers to the flow of electrical current. It is measured in ohms and can have an impact on the sound quality of a soundbar. In general, a lower impedance means that the soundbar will be able to draw more power from the amplifier, resulting in louder and clearer sound. However, this also means that the soundbar may be more prone to distortion at high volumes.
Sensitivity:
Sensitivity measures how efficiently a soundbar converts electrical power into acoustic power (i.e., sound). It is usually measured in decibels (dB) and is an indicator of how loud a soundbar can get. A higher sensitivity means that the soundbar will be louder for a given amount of power.
Harmonic distortion:
Harmonic distortion is a measure of how much the soundbar distorts the original audio signal. It occurs when the soundbar introduces new frequencies that were not present in the original signal. Harmonic distortion is usually expressed as a percentage, with lower percentages indicating less distortion.
Signal-to-noise ratio:
The signal-to-noise ratio (SNR) measures the amount of signal (i.e., the audio you want to hear) compared to the amount of noise (i.e., unwanted sound) that the soundbar produces. A higher SNR means that the soundbar produces less noise relative to the desired audio signal.
Dynamic range:
Dynamic range measures the difference between the loudest and quietest sounds that a soundbar is capable of producing. A higher dynamic range means that the soundbar is capable of producing a wider range of sounds, which can be especially important for movies and music with a lot of dynamic variation.
Crossover frequency:
The crossover frequency is the frequency at which a soundbar switches from one speaker (e.g., the main speakers) to another (e.g., a subwoofer). This is important because different speakers are better suited to producing different frequencies, and by splitting the audio signal into different frequency bands, a soundbar can ensure that each speaker is producing the frequencies that it’s best suited for.
Sound quality metrics are an essential aspect of choosing a soundbar that best suits your needs. Each metric provides valuable information about the soundbar’s performance and can help you make an informed decision. It’s important to keep in mind that no soundbar is perfect and that different soundbars may prioritize different metrics depending on their intended use. By considering each of these metrics and your personal preferences, you’ll be able to find a soundbar that delivers the sound quality you’re looking for.
According to a survey conducted by Statista in 2020, sound quality is the most important feature for consumers when purchasing a soundbar, with 42% of respondents ranking it as the top factor.
Sound Quality Standards
In addition to sound quality metrics, there are also several sound quality standards that can help you compare and evaluate different soundbars. Here are some of the most common standards:
THD (Total Harmonic Distortion):
THD is a standard that measures the amount of harmonic distortion in a soundbar. It’s expressed as a percentage of the original signal, with lower percentages indicating less distortion. The lower the THD, the cleaner and more accurate the sound.
IMD (Intermodulation Distortion):
IMD is a measure of the distortion that occurs when two or more frequencies are played simultaneously. It’s expressed as a percentage, with lower percentages indicating less distortion. IMD is especially important for music and movies with complex soundscapes, as it can impact the clarity and separation of different sounds.
SNR (Signal-to-Noise Ratio):
SNR is a standard that measures the amount of signal (i.e., the audio you want to hear) compared to the amount of noise (i.e., unwanted sound) that a soundbar produces. A higher SNR indicates less noise and cleaner, clearer sound.
CEA-2010:
CEA-2010 is a set of standards developed by the Consumer Electronics Association to help consumers compare the performance of different soundbars. It includes several metrics, including frequency response, distortion, and dynamic range.
Dolby Atmos:
Dolby Atmos is a sound technology that uses object-based audio to create a more immersive listening experience. It allows soundbars to place sound effects in specific locations around the listener, creating a more realistic and dynamic soundstage.
DTS:X:
DTS:X is another object-based audio technology that works in a similar way to Dolby Atmos. It allows soundbars to create a more immersive sound experience by placing sounds in specific locations around the listener.
When evaluating different soundbars, it’s important to consider both sound quality metrics and standards. Metrics like THD, IMD, SNR, and frequency response provide valuable information about the sound quality of a soundbar, while standards like CEA-2010, Dolby Atmos, and DTS:X can help you compare and evaluate different models. Ultimately, the best soundbar for you will depend on your personal preferences and needs, but by considering both metrics and standards, you’ll be able to make a more informed decision.
In another study conducted by Crutchfield, a leading retailer of audio equipment, the most common sound quality issues in soundbars are poor bass response and lack of clarity in dialogue. The study found that soundbars with separate subwoofers and clear voice enhancement features can help address these issues.

Factors Affecting Sound Quality
While sound quality metrics and standards are important, there are also several factors that can impact the sound quality of a soundbar. Here are some of the most common factors:
Driver size and type:
The drivers are the components of the soundbar that produce sound. The size and type of driver can have a significant impact on sound quality. For example, larger drivers can produce deeper bass and fuller sound, while smaller drivers are better suited for higher frequencies.
Number of drivers:
The number of drivers in a soundbar can also impact the sound quality. More drivers generally mean a fuller and more dynamic sound. However, having too many drivers can also result in muddiness and distortion.
Enclosure design:
The design of the soundbar enclosure can also impact the sound quality. Enclosures that are too small or too large can result in distorted or boomy sounds. A well-designed enclosure can help to produce clean, accurate sound.
Amplifier power:
The power of the amplifier can also impact the sound quality of a soundbar. A more powerful amplifier can produce louder and more dynamic sound, but too much power can result in distortion and other issues.
Power Consumptions
The power consumption of a soundbar may affect the audio quality in some cases, but it’s not the only factor to consider. The wattage of a soundbar indicates how loud it can get, but not necessarily how good it sounds. A soundbar with a higher power consumption may be able to produce louder and more dynamic sound, but it may also consume more energy and generate more heat. A soundbar with a lower power consumption may be more energy-efficient and eco-friendly, but it may not be able to fill a large room with sound. Ultimately, the best soundbar for you depends on your personal preferences, your budget, and your room size.
Room acoustics:
The acoustics of the room in which the soundbar is placed can also impact the sound quality. For example, a room with hard surfaces can result in more echoes and reverberation, while a carpeted room can help to absorb sound and produce cleaner sound.
While sound quality metrics and standards are important, they don’t tell the whole story when it comes to evaluating the sound quality of a soundbar. Factors like driver size and type, the number of drivers, enclosure design, amplifier power, and room acoustics can all impact sound quality. When evaluating different soundbars, it’s important to consider these factors as well as the sound quality metrics and standards to get a complete picture of the sound quality.
