Step 1
Choose the right filter
We match attenuation to your workplace sound profile and communication needs.
Information
Custom Impulse Work combines a precise custom fit with a non-linear impulse filter: the harder the impact, the more the filter attenuates. Built for teams working around sudden impact sound who need to stay aware of their surroundings between peaks.
Description
Impulse-filtered protection for workplaces with sudden peak noise and impact sound.
Impulse-safe attenuation with lower isolation between peak-noise events.
Attenuation values
Attenuation values in decibels (dB).
Impulse (
filter)
Impulse 9* (
filter)
Ludicrous (
filter)
* Impulse 9: indicative curve based on the manufacturer's H/M/L values — at SNR 15 dB it falls below the CE-certification threshold for hearing protection (no EN 352-2 measurement).
| Filter | Low | Mid | High | SNR |
|---|---|---|---|---|
| Impulse filter | 17 dB | 19 dB | 22 dB | 21 dB |
| Impulse 9 (beige) | 7 dB | 12 dB | 19 dB | 15 dB |
Impulse 9 (beige): the same peak attenuation (IPIL) on shots as the standard Impulse filter, but a lower constant attenuation. Please note: that attenuation is below the threshold for CE certification (EN 352-2), and Impulse 9 cannot be combined with the Click upgrade.
| Ludicrous | 26 dB | 26 dB | 27 dB | 28 dB |
|---|
Peak attenuation for impulse noise (ANSI S12.42): the louder the bang, the more the filter attenuates.
| Peak level | Peak attenuation (IPIL) |
|---|---|
| 133 dB | 28 dB |
| 150 dB | 32 dB |
| 164 dB | 34 dB |
