German term

Knallbelastung

German to English Medical Military / Defense Not happy with "explosion load".
Context: Grenzpegeldiagramm zur Hörschädenvermeidung bei Knallbelastung.
Proposed translations (English)
4 impulse noise exposure
3 +3 exposure to blast (overpressure) / blast load
4 noise exposure // acoustic trauma
References
blast overpressure

Discussion

Ramey Rieger (X) Jan 17, 2022:
blast impact Maximum acoustic levels of blast impact on hearing to avoid aural damage
Or something like that
uyuni Jan 17, 2022:
Please see below... 'Knalltrauma' = 'acoustic shock' (a single incident/experience with impact on the inner ear due to a high and short sound pressure level)
'Lärmbelastung' = 'acoustic load' (a persistent and or repetitive impact of high sound pressure levels)

At least in my perception...
Try find something similar or in between, depending on context (repetitive 'Knalltraumata').

You might also consider "impact" instead of "load".

agree philgoddard : Though I think of "load" as applying to buildings.

See the cited source, in which it says "A baseline audiogram and tympanogram are desirable for all patients exposed to a significant blast load and should follow ENT assessment."
agree Cillie Swart : Yes Definitely. Thanks !!

neutral uyuni : Wie Phil lässt mich "blast load" auch zuerst an die erforderliche Sprengstofflast für (beispielsweise) Hochhaus- oder Brückensprengungen denken, während "Knallbelastung" m.E. die rein akustische Konnotation repetitiver auditiver Traumata transportiert...

blast overpressure

Quite frankly I'd have been happy with "blast exposure", but "blast overpressure" seems to be the word.

"As the ear is the organ most sensitive to BLAST OVERPRESSURE, the most frequent injuries seen after blast exposure are those affecting the ear. BLAST OVERPRESSURE affecting the ear results in sensorineural hearing loss, which is untreatable and often associated with a decline in the quality of life. "
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6380998/#:~:tex...

The case histories of five patients who experienced BLAST OVERPRESSURE in excess of 200-dB peak pressure level are presented. Despite the significance of the sound pressure levels received in a military training accident and the severe injuries that resulted from the blast, these individuals experienced substantial improvement of hearing 1 year later.
https://pubmed.ncbi.nlm.nih.gov/9101454/

BLAST OVERPRESSURE of sufficient intensity can produce injury to various organ systems. Unprotected ears result in the auditory system being the most susceptible
https://pubmed.ncbi.nlm.nih.gov/9217313/

Overpressure is a type of pressure brought about by shockwaves more powerful than average atmospheric pressure. These shockwaves may be caused by several things, like an explosion or sonic boom.
Overpressure can be used in the measurement of the effects of thermobaric bombs and nuclear weapons.
Overpressure is also known as BLAST OVERPRESSURE.
https://www.corrosionpedia.com/definition/840/overpressure

Overpressure (OR BLAST OVERPRESSURE) is the pressure caused by a shock wave over and above normal atmospheric pressure. The shock wave may be caused by sonic boom or by explosion,
