Noise reduction through HDSX-box in the bar of a cruise ship

HDSX visits an ocean liner. Shortly after boarding, all guests gather in the central bar and toast the upcoming sea voyage. Here in this bar, which is spread over three floors and connected by a large, open staircase, powerful sound systems provide the sound. In addition to a stage area with clearly bass-enhanced sound, there are numerous loudspeakers evenly distributed.

To test the HDSX box, we found a well-filled bar with loud music. The volume level was slightly raised. The result: the bar guests spoke louder to each other than is normally necessary because the overall noise level was higher than normal conversation volume. Another reason: the music was only audible for a short time and was played at a generally pleasant volume, but as soon as the pieces of music became more dynamic in the chorus or the powerful bass of the system became more present due to the changing style of music, the conversations were drowned out. The result: the conversation volume was raised again. The volume level rose considerably within 20 minutes.

With the use of the HDSX box, the situation changes significantly within minutes. Because the music volume is predictable and the same at all times - regardless of the genre of music or the point in the piece being played - conversations gradually become quieter. There is no longer any reason to want to speak louder than the music, as the music reliably remains the same volume. This improves the atmosphere for all guests, and the time spent in the bar is perceived as less stressful. This clear effect can be repeated: after the HDSX box is switched off, the music volume oscillates again, resulting in significantly higher conversation volume.
