La timpanometría muestra el movimiento del tímpano.

Timpanometría means tympanometry, a medical test that measures how the eardrum responds to changes in pressure.

It is not an everyday word. It is mainly used in medical or audiology contexts. A Spanish speaker outside that context may understand it if they know medical vocabulary, but it is definitely a technical term.

Spanish nouns have grammatical gender. Timpanometría is feminine, so it takes the feminine singular article la.

• la timpanometría
• not el timpanometría

Many nouns ending in -ía are feminine:

• la biología
• la cirugía
• la audiometría
• la timpanometría

Because the subject is La timpanometría, which is singular.

So the verb must also be singular:

• La timpanometría muestra... = Tympanometry shows...

If the subject were plural, then the verb would be plural:

• Las pruebas muestran... = The tests show...

Muestra is the third-person singular present indicative form of mostrar.

Here it means:

• shows
• demonstrates
• reveals

In scientific or medical writing, the present tense is very common because it states facts or general descriptions.

Because in Spanish, de + el contracts to del.

So:

• de + el = del

That is why you say:

• el movimiento del tímpano

not:

• el movimiento de el tímpano

This contraction is required in normal Spanish, except in a few special cases, such as when El is part of a proper name.

Tímpano means eardrum.

It is a masculine noun:

• el tímpano

In anatomy, you may also hear more formal expressions like:

• la membrana timpánica = the tympanic membrane

But tímpano is the common straightforward term.

Because movimiento is a masculine singular noun.

So:

• el movimiento = the movement

This noun comes from the verb mover (to move), but in this sentence it is a noun, not a verb.

The accent marks show which syllable is stressed.

• timpanometría → stress on the -rí- syllable
• tímpano → stress on the tím- syllable

These written accents are important in Spanish because they guide pronunciation and sometimes distinguish words.

A rough pronunciation guide:

• timpanometría: tim-pa-no-me-TREE-a
• tímpano: TEEM-pa-no

Yes, mostrar works very well here. In a medical or technical context, it can mean shows, displays, or reveals.

Depending on the context, Spanish could also use:

• indicar = to indicate
• medir = to measure
• evaluar = to evaluate
• registrar = to record

But in your sentence, muestra is natural and clear.

This is the most neutral and natural word order in Spanish:

• Subject + verb + object
• La timpanometría muestra el movimiento del tímpano.

Spanish does allow more flexibility than English, but this standard order is the most common, especially in informative or technical writing.

A different order might be possible for emphasis, but it would usually sound less neutral.

Yes, depending on the context, el movimiento del tímpano could sometimes be understood as the movement or the mobility of the eardrum.

In technical English, mobility may sound more natural in some medical explanations. But the Spanish noun here is literally movement, and that is a normal and understandable choice.

By itself, it sounds like a general statement about what tympanometry does:

• Tympanometry shows the movement of the eardrum.

If you wanted to describe a specific past result, Spanish would probably use another tense, for example:

• La timpanometría mostró... = The tympanometry showed...

So the present tense here suggests a general description or definition.

A careful pronunciation would be roughly:

la tim-pa-no-me-TREE-a MWES-tra el mo-bi-MYEN-to del TEEM-pa-no

A few pronunciation notes:

• ti in tímpano sounds like tee
• muestra begins with mwe-
• ll does not appear here, so there is nothing unusual there
• r in muestra is a light Spanish r
• del is pronounced as one short word: del

Yes, especially in a medical, educational, or technical context. It sounds natural and correct.

In more everyday language, someone might explain it in a less technical way, such as:

• La timpanometría permite ver cómo se mueve el tímpano.
• La timpanometría mide cómo responde el tímpano.

But your original sentence is perfectly normal in formal or professional Spanish.
