Functions of TV speakers

This section covers common challenges and solutions related to TV speakers. We highlight why the sound quality of modern televisions often falls short of expectations and what problems can arise with speech intelligibility and sound mixing. In addition, we show the advantages of external TV speakers and how specific solutions can help to remedy common volume problems. More detailed information can be found in the individual sections, which provide more comprehensive and in-depth explanations where necessary.

Why TV speakers?

The sound quality of integrated TV speakers is often limited, as the development of increasingly thin televisions leaves little room for powerful speakers. This results in flat and unbalanced sound that fails to meet expectations for a high-quality audio experience on many modern televisions. Lower frequencies, such as bass, often do not come into their own, which can lead to an incomplete listening experience, especially when watching action movies or listening to music. In addition, many TV speakers are directed backwards or downwards, which further weakens the sound as it is not directed directly at the listener.

Another important factor for sound is room acoustics. Rooms with hard surfaces such as tiles or glass reflect sound and create echoes that can distort the sound. On the other hand, soft materials such as carpets and furniture absorb sound, which can make dialogue difficult to understand. Simple adjustments to the speaker position or additional acoustic measures such as carpets or curtains can significantly improve sound quality by distributing sound more evenly throughout the room.

In addition, the compression of audio signals in digital transmissions and streaming services often impairs sound quality. Compressed formats lose a lot of detail and nuance, resulting in less clear playback. Dialogue is particularly affected, as the subtle differences in speech are lost. The use of uncompressed audio formats or high-quality external sources can significantly improve sound quality in this case.

The incomprehensibility of dialogue is another problem that is particularly noticeable in modern productions. In many films and series, sound effects and music are emphasized so strongly that they drown out the dialogue. In addition, complex technologies such as Dolby Atmos can make it difficult to separate dialogue and effects if the speakers or mixing are not optimally adjusted. External speakers or soundbars that are specifically designed to improve speech intelligibility can help to make the dialogue clear and distinct.

For many people, especially seniors or those with hearing problems, watching television can be challenging because certain frequencies are difficult to understand. Speakers that are tailored to individual hearing needs offer a solution. These systems make it possible to optimize sound so that dialogue is easier to hear, which significantly improves the television viewing experience.

Although technologies such as Dolby Atmos are revolutionizing the listening experience, they have their limitations. Especially with complex soundscapes, it can be difficult to achieve a clear separation between dialogue and sound effects. Proper speaker setup and calibration is therefore crucial to take full advantage of these technologies.

Another common problem with TV speakers is uneven volume. Volume fluctuations between dialogue, music, and commercials can be distracting for viewers and mean that the volume has to be constantly adjusted. Modern soundbars and speaker systems usually offer a feature that compensates for these fluctuations and ensures a consistent listening experience.

Why am I having problems with the TV?

Modern televisions offer impressive picture quality, but the sound quality often falls short of expectations. This is mainly due to the design of the devices. The built-in speakers are usually small and adapted to the flat design of the TVs. The limited space for powerful speakers capable of reproducing low frequencies and bass results in a flat sound that is insufficient, especially for dialogue or music, as well as for intense sound effects in movies and series.

Another problem is the reduced sound quality caused by digital transmissions, which are common in many modern televisions. Compressed audio signals and bandwidth limitations reduce sound detail and are particularly noticeable when playing back dialogue. This technical limitation means that the sound does not achieve the clarity and depth necessary for a good television experience.

The development of increasingly flat televisions has also had a negative impact on sound quality. In the past, thicker models could accommodate larger speakers that were capable of producing a fuller and clearer sound. However, the trend toward ultra-slim devices has led to a significant decline in acoustic performance. Especially with modern Ultra HD and 4K televisions, which deliver incredible picture quality, sound quality is lost due to the flat design. Another structural problem is the placement of the TV speakers. These are often directed downwards or backwards, which means that the sound is not directed directly at the viewer. This results in a less precise, diffuse sound and reduces sound reproduction. The combination of these technical and structural challenges makes it clear why the integrated speakers in TVs are often not sufficient to provide a truly impressive listening experience.

Challenges and solutions

Speech intelligibility in TV sound is a challenge, especially in modern productions where sound effects and music often drown out the dialogue. In action films or music-heavy series in particular, the spoken words tend to fade into the background. This is especially problematic when the dialogue is difficult to understand, which is often the case with integrated TV speakers, as they do not allow for a clear separation between speech and other sounds. Another problem arises for people with impaired hearing who have difficulty hearing certain frequencies, resulting in distorted or unclear sound.

The placement and type of speakers, especially in thin TVs, also contribute to the sound being perceived as less direct and precise. External solutions such as soundbars, which are specifically designed to make dialogue clearer and improve the sound balance, can help here. They offer functions to enhance speech intelligibility and are able to optimize the sound mix between music, effects, and dialogue.

Another common problem is uneven volume between different formats such as movies and TV series. In movies, the sound is often louder and more dramatic, resulting in volume fluctuations that make it difficult to hear. Commercials are also intentionally mixed with louder sound, leading to annoying volume jumps. Modern speaker systems can compensate for these fluctuations, making the listening experience more enjoyable and consistent.

The right audio equipment, especially when equipped with technologies such as Dolby Atmos or special voice modes, can effectively address these challenges and significantly improve sound quality.

External TV speakers, such as soundbars, compact speakers, standard speakers, or special speaker systems, offer a significant improvement in sound quality compared to built-in TV speakers. They not only deliver clearer and more precise dialogue, but also a wider soundstage and deeper frequencies that are often lacking in flat-screen TVs. Especially with complex soundscapes, such as those found in action movies or music productions, better speaker placement and advanced technology ensure that the sound is reproduced more clearly and dynamically.

There are many advantages to external TV speakers. One key advantage is their versatility. They can be connected to various sources such as TVs, smartphones, or tablets and often offer numerous connection options such as HDMI ARC, optical inputs, or Bluetooth, which increases flexibility. Many models also offer additional features such as Dolby Atmos or DTS:X, which provide a spatial sound experience and give you the feeling of being right in the middle of the action.

External speakers also offer improved volume and sound balance. Choosing the right speakers can compensate for unpleasant volume fluctuations between dialogue and background noise, which is particularly beneficial for people with hearing problems. Even in larger rooms or open-plan living areas, an external speaker system ensures that the sound is distributed evenly and voluminously, making the TV experience more enjoyable for all viewers.

Many television viewers notice that the volume is often inconsistent across different TV programs, platforms, and formats. With streaming services such as Netflix, Amazon Prime Video, public broadcasters' media libraries, and even different TV programs, the volume varies due to different compression and audio formats. These differences lead to fluctuating sound quality and impair the intelligibility of dialogue. Streaming services, for example, tend to compress audio signals more heavily, which can lead to a loss of detail and clarity.

Modern televisions have volume controls that compensate for some of the volume fluctuations. This feature can be helpful in stabilizing the volume during program content and commercials, but it does not achieve the precision of an external speaker system or a TV speech amplifier. External solutions significantly improve speech intelligibility by emphasizing frequencies that are important for speech, making dialogue clearer and easier to understand.

External TV speakers are particularly beneficial for users who want to improve the sound quality of their television. They are especially valuable for people who regularly watch movies or series and want clear dialogue reproduction and richer sound. These systems are also ideal for home theater enthusiasts who want to add more depth to sound effects and music. A key advantage of external speakers is that they are also helpful for seniors. Hearing often deteriorates with age, which makes it particularly difficult to understand dialogue. Especially with integrated TV speakers, which often struggle with higher or lower frequencies, dialogue often disappears in the cacophony of music and effects.

External speakers, especially those with a "dialogue mode" such as the OSKAR TV speaker, offer a significant improvement here. These models emphasize the mid and high frequencies to increase speech intelligibility, while reducing lower frequencies. The ability to customize the sound also helps to optimize the audio according to your own needs. In addition, external speakers offer the advantage of directing the sound specifically toward the viewer, which is particularly beneficial for televisions with downward or rear-facing speakers.

For seniors who live in smaller apartments, compact external speakers offer a space-saving yet powerful solution. Not only do they improve sound quality, they also make the TV experience much more enjoyable and understandable for people with hearing problems. External speakers are therefore a worthwhile investment for anyone who wants to optimize the speech intelligibility and overall sound quality of their TV.
