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
Testy odbyły się w dwóch lokalizacjach: w naszym Showroomie w Warszawie oraz w biurze w Szczecinie. Do udziału zaprosiliśmy zarówno naszych obecnych, jak i potencjalnych klientów, a także znajomych, którzy interesują się nowoczesnymi technologiami. Ich opinie były dla nas kluczowe, ponieważ to właśnie odbiorcy technologii decydują o tym, jakie parametry są dla nich najważniejsze. Podczas wizyty w Showroomie uczestnicy mieli okazję nie tylko obejrzeć najwyższej jakości obrazy holograficzne, ale również doświadczyć interakcji z dźwiękiem, który je dopełnia. Do testów wykorzystaliśmy 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.
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.
