Bluetooth Hologram Speaker Test – Ledholo Experiment Results

With the rapid development of holographic technologies, the quality of the sound accompanying the projected images is becoming increasingly important. At Ledholo, we've been working for years to perfectly reproduce reality in the form of holograms, but to achieve an even more immersive experience, impeccable sound quality is essential. We decided to test Bluetooth speakers compatible with our holograms to see which device best complements our holographic projectors.

Experiment locations and participants

The tests took place at two locations: our showroom in Warsaw and our office in Szczecin. We invited both our current and potential customers, as well as friends interested in modern technologies, to participate. Their opinions were crucial to us, because it is the users of the technology who decide which features are most important to them. During their visit to the Showroom, participants had the opportunity not only to view top-quality holographic images but also to experience the sound that complements them. For the tests, we used holographic projector Ledholo MatrixX 1.3NC.72, which generated the image of the character and its voice was transmitted via three different Bluetooth speaker models: BOSE, JBL and TONSIL.

Test methodology

To ensure the objectivity of the research, we prepared precise questions regarding various sound parameters. Participants assessed:

sound clarity – whether the voice generated by the hologram was clear, natural and free from interference,
bass quality – were the low tones well balanced and did not overwhelm the entire sound spectrum,
balance of mid-range and high tones – whether the speech was natural and whether details were clearly audible,
sound spatiality – did the sound seem enveloping and realistic,
sound quality at different volume levels – whether there was any distortion,
overall impressions and preferences – which speaker sounded best according to the participant.

Each tested loudspeaker was evaluated under identical acoustic conditions, and participants had the opportunity to compare the sound side by side to ensure their ratings were as accurate as possible.

Test results

After collecting all the reviews, it turned out that the highest-rated speaker was the BOSE model. Participants praised it primarily for:

extremely clear and natural sound,
well-balanced bass and treble,
excellent sound quality regardless of the volume level,
spatiality of the sound, which made the hologram seem more realistic.

The JBL, despite its good dynamics and strong bass, was considered less precise in the midrange, which could affect the intelligibility of the hologram's speech. Meanwhile, the TONSIL won praise for its natural sound but fared slightly less well in terms of spatiality.

Conclusions and further plans

Our study confirmed that sound quality is crucial to the experience of holographic presentations and communication. Choosing the right speaker can significantly impact the sense of realism and the quality of interaction with the hologram. Based on the results of the experiment, we will recommend BOSE speakers to our clients as the optimal choice for our holographic projectors. However, our testing does not end with this one series—in the future, we also intend to test other models and experiment with surround sound systems to further enhance the quality of the audiovisual experience.
