Calibramos el audífono durante la adaptación audioprotésica.

Calibramos is the 1st person plural form of calibrar: we calibrate / we calibrated.

This form is a little tricky because in Spanish it can be:

• present indicative: we calibrate
• preterite: we calibrated

So calibramos el audífono can mean either we calibrate the hearing aid or we calibrated the hearing aid, depending on context.

In a technical or procedural sentence like this, it often sounds like:

• a description of what professionals do in general: We calibrate the hearing aid during the fitting process
• or a report of what was done, if the surrounding context is in the past

Spanish often relies on context to make that clear.

Spanish uses articles more often than English, especially with concrete nouns.

Here, el audífono means the hearing aid. It refers to a specific device, probably the one being fitted or adjusted for the patient.

If you removed the article and said Calibramos audífono, it would sound wrong in standard Spanish.

So:

• el audífono = the hearing aid
• un audífono = a hearing aid

Yes, in Spain audífono normally means hearing aid.

That matters because English speakers may see audio- and guess something more general, like headphones or earphones. But in Spain:

• audífono = hearing aid
• auriculares = headphones / earphones

So in this sentence, audífono is clearly the medical device, not something used for listening to music.

Durante means during.

It introduces the time period or process in which the action happens:

• Calibramos el audífono durante la adaptación audioprotésica.
• We calibrate the hearing aid during the audioprosthetic fitting process.

It is the natural choice when you want to say that one action happens in the course of another process.

Compare:

• durante la consulta = during the appointment
• durante la adaptación = during the fitting/adaptation process

This is a technical expression.

• adaptación = fitting, adjustment, adaptation process
• audioprotésica = related to hearing aids / audioprosthetics

So adaptación audioprotésica refers to the professional process of fitting and adjusting a hearing aid for a patient.

It is not a very everyday phrase. It sounds:

• clinical
• professional
• specialized

A learner should recognize that this is medical or technical Spanish, not casual conversation.

Because it agrees with adaptación, which is a feminine noun.

In Spanish, adjectives must agree in gender and number with the noun they describe.

• la adaptación → feminine singular
• therefore: audioprotésica → feminine singular

If the noun were masculine, the adjective would change too. For example:

• el proceso audioprotésico

So the ending -a here is about agreement, not about changing the core meaning.

In Spanish, adjectives often come after the noun, especially in:

• technical language
• classifications
• objective descriptions

So adaptación audioprotésica is the normal order.

This is very common in Spanish:

• tratamiento médico
• equipo técnico
• revisión auditiva

Putting the adjective first would sound unusual here and would not be standard in this kind of professional phrase.

Possibly, but they are not exactly the same.

• ajustar = to adjust
• calibrar = to calibrate

Calibrar sounds more technical and precise. It suggests setting the device correctly according to specific measurements or parameters.

Ajustar is a bit broader and can mean simply making the device fit or work better.

So:

• calibramos el audífono = we calibrate the hearing aid
• ajustamos el audífono = we adjust the hearing aid

In a clinical or technical context, calibramos may be the better choice if the focus is on accurate settings.

Because el audífono is a thing, not a person.

In Spanish, the personal a is used before a specific human direct object (and sometimes pets or personified beings), for example:

• Vemos al paciente. = We see the patient.

But here:

• Calibramos el audífono.
• The direct object is the hearing aid, an object.

So no a is needed.

It is definitely formal / technical Spanish.

Words like:

• calibramos
• audífono
• adaptación audioprotésica

make it sound professional, probably from:

• a clinic
• a medical report
• a training manual
• a specialist explaining a procedure

A native speaker would understand it, but adaptación audioprotésica is not something most people would say in casual conversation unless they work in that field.

Yes. Spanish word order is fairly flexible.

For example, you could also say:

• Durante la adaptación audioprotésica, calibramos el audífono.

This version puts the time/process phrase first for emphasis.

Both are correct, but the original version is very natural because it follows a common pattern:

verb + object + time/process phrase

So:

• Calibramos el audífono durante la adaptación audioprotésica.

sounds smooth and neutral.

The accent marks show which syllable is stressed.

• audífono → stress on dí
  Pronounced roughly: au-DI-fo-no
• adaptación → stress on the last syllable ción
  Roughly: a-dap-ta-THYON in much of Spain, or a-dap-ta-SYON in Latin America
• audioprotésica → stress on té
  Roughly: au-dio-pro-TE-si-ca

For a learner of Spanish from Spain, also note that many speakers in Spain pronounce c before i/e as a th sound:

• adaptación → -ción with th
• protésica → si stays s, because it is written with s, not c

It exists in everyday Spanish, but it is more common in:

• technical contexts
• scientific contexts
• medical/device contexts

You can calibrate:

• instruments
• machines
• measuring devices
• hearing aids

So it is a normal verb, but not one of the most common verbs in casual daily conversation.

Both are possible, but fitting is often better in this context.

A literal translation is:

• adaptación = adaptation

But in hearing-aid or medical-device contexts, English often uses:

• fitting
• fitting process
• adjustment/fitting session

So even though the Spanish word is adaptación, the most natural English equivalent may be fitting rather than a word-for-word adaptation.

That is a good example of how medical or technical translation often depends on usage, not just dictionary meaning.
