How to Optimize Audio on ELO Kiosks

Speaker Positioning

Audio dispersion determines perceived quality.
If speakers fire directly against a wall, reflections cause phase cancellation that dulls speech.
Angle built-in speakers toward the listening zone or use small external speakers placed near user height.

For countertop kiosks, position speakers under the display’s edge, facing downward at 30 degrees. This prevents direct reflections into glass surfaces while still projecting sound clearly.

Acoustic Design for Public Areas

High ambient noise environments such as malls or terminals require directional sound. Add small hooded speakers or sound domes that focus audio only where the user stands.
This reduces noise pollution and improves intelligibility.

Volume Control and Limiting

Use the device OS or app to cap maximum output at around 70 percent of total. Above that, amplifier distortion rises.
Dynamic range compression can keep soft voices audible while preventing clipping on loud effects.

If the kiosk operates across multiple shifts, schedule automatic volume adjustments based on time of day.

Accessibility and Private Audio

Add 3.5 mm jacks or Bluetooth output for headphones where privacy is needed, especially in healthcare or payment kiosks.
For accessibility, provide visual confirmation cues for every audio event.

Maintenance

Dust and vibration can loosen speaker connectors over time. Inspect quarterly.
If you notice rattling, re-tighten mounts and check gaskets.

Example

A city information kiosk network used ELO I Series displays with external mini soundbars. After tuning equalizer presets for vocal clarity and adding a nighttime volume schedule, customer satisfaction scores rose by 18 percent.

Final Thoughts

Audio is as critical as visuals in user experience. Proper orientation, limiting, and equalization deliver clarity without disturbance, completing the professional impression of your ELO kiosk.
