6 reasons why TV sound is often difficult to understand

TV sound that is difficult to understand can have various causes. The most common reasons are described here:

1. Mixing of audio tracks:
Often, dialogue, music and sound effects are not mixed optimally. This can lead to the dialogue being drowned out by loud background noise, which impairs intelligibility.

2. Poor sound quality of the soundtrack:
When audio is transmitted across different platforms and devices, quality can suffer. Compression techniques used in streaming services and digital transmissions can reduce the clarity of the audio.

3. Acoustics of the room:
The acoustics of the room where the TV is located can also play a role. Hard reflective surfaces such as walls and windows can cause echoes and distort sound, while soft materials such as carpets and curtains can absorb sound and improve intelligibility.

4. Speaker quality and placement:
The quality and placement of the TV speakers have a major impact on sound reproduction. Built-in speakers in TVs are often small and not optimally positioned, which can lead to poor sound.

5. Audience hearing ability:
Individual hearing ability varies. Older people in particular often have difficulty hearing high frequencies, which can affect the intelligibility of dialogue. This can be improved by hearing aids or special audio devices tailored to the individual's needs.

6. Most films are produced using Dolby technology, but this often cannot be played back optimally. There are various reasons for this:

a) Complexity of surround sound mixes:
Dolby technologies are designed to provide an immersive surround sound experience. However, in complex surround sound mixes, dialogue may need to be brought to the forefront to be clearly audible over the numerous sound effects and music. If this is not mixed optimally, dialogue can get lost.

b) Unsuitable audio devices for Dolby Sound:
Not all TVs and speaker systems are optimized to play Dolby sound. If the viewer's audio system is unable to play Dolby sound correctly, the result may be distorted or unclear sound. Soundbars and small speaker systems in particular may struggle to deliver the full effect of Dolby Surround Sound, which may affect intelligibility.

c) Lack of compatibility and setting options:
Some TVs and home theater systems do not offer the option to adjust Dolby sound to individual needs. Without the ability to calibrate the sound or control the dialogue volume separately, it can be difficult to achieve clear and intelligible sound reproduction.

d) Automatic dynamic compression:
Dolby sound systems often use automatic dynamic compression to balance loud and quiet passages. However, this feature can cause quiet dialogue to become too quiet and loud sound effects to become too dominant, which can affect the intelligibility of conversations.
In summary, the use of Dolby technologies in conjunction with other factors can result in television sound being less intelligible if all components are not optimally coordinated.

The HDSX TV Sound Optimizer is designed to solve all of these problems, regardless of the format or device used. Its HDSX - High Definition Sound Expansion technology ensures clarity and intelligibility of dialogues by amplifying speech frequencies and reducing background noise. This ensures that spoken words can be heard more clearly and distinctly.

The technology balances the different audio elements (dialogue, music, sound effects) so that they work harmoniously together and none of the elements is overly dominant.

The HDSX TV Sound Optimizer automatically adjusts the sound to the content being played. This means that no matter what genre the program is - be it a movie, a sports broadcast or a news program - the sound is set to the optimum level.

Last but not least, the device does not require any complicated settings or adjustments by the user. It works in the background and optimizes the sound automatically, so that the user enjoys an improved sound experience without having to intervene.

In summary, HDSX TV Sound Optimizer is an advanced audio technology that aims to optimize the TV experience through improved sound quality and dialogue intelligibility.
