Comparamos el acúfeno con el zumbido.

Comparamos is the first person plural form of comparar — in other words, we compare or we compared, depending on context.

So the subject is nosotros (we), even though Spanish usually leaves the subject pronoun unstated.

• (Nosotros) comparamos = we compare / we compared

For many -ar verbs, the present and the preterite forms are identical in the nosotros form.

With comparar:

• Present: comparamos = we compare
• Preterite: comparamos = we compared

So you need context to know which one is meant. If the meaning shown to the learner is we compare, that is coming from context, not from the verb form alone.

Spanish often uses the definite article more than English does.

Here, el acúfeno and el zumbido can refer to:

• a specific case already known in context, or
• the concepts in a general or technical sense

In English, we might sometimes omit the article more easily, but in Spanish it is very normal to say:

• el acúfeno
• el zumbido

especially in medical, explanatory, or descriptive language.

Because comparar is commonly used with con to mean to compare X with Y.

Pattern:

• comparar algo con algo = to compare something with something

So:

• Comparamos el acúfeno con el zumbido = We compare tinnitus with buzzing / the buzzing

Yes. Spanish allows both patterns:

• comparar A con B
• comparar A y B

Both are correct.

Using con often makes the relationship especially clear for English speakers, because it matches compare A with B.

So all of these can work:

• Comparamos el acúfeno con el zumbido
• Comparamos el acúfeno y el zumbido

The version with con is very standard and natural.

Even if the general meaning is already known, the nuance matters:

• acúfeno is a medical or technical term for tinnitus
• zumbido is a more general word meaning buzzing, humming, or a similar sound

So in this sentence, acúfeno sounds more clinical, while zumbido refers more to the sound itself.

Yes, but it is somewhat formal or medical.

In everyday speech, people in Spain may also say things like:

• tinnitus
• pitido en el oído
• zumbido en los oídos

So acúfeno is perfectly correct, but it sounds more technical than some everyday alternatives.

It is pronounced roughly as a-KOO-fe-no.

The written accent in acúfeno shows that the stress falls on cú:

• a-CÚ-fe-no

Without the accent mark, Spanish stress rules would suggest a different pronunciation, so the accent is necessary.

They are singular because the sentence is talking about each thing as a single concept or type of phenomenon.

So:

• el acúfeno = tinnitus, as a condition or phenomenon
• el zumbido = the buzzing, as a type of sound

Spanish often uses the singular this way when speaking generally or analytically.

Not normally.

Comparamos means we compare or we compared, not let’s compare.

To say let’s compare, Spanish would usually use:

• comparemos
• vamos a comparar

So:

• Comparemos el acúfeno con el zumbido = Let’s compare tinnitus with buzzing

The basic word order here is very natural:

• Comparamos el acúfeno con el zumbido

Spanish word order is often flexible, but this is the most neutral pattern:

• verb + direct object + con + second term

You could change the order for emphasis, but in normal explanatory language this version is the clearest.

Because Spanish only contracts a + el and de + el:

• a + el = al
• de + el = del

But con + el does not contract.

So:

• con el zumbido is correct
• col does not exist

Yes. It sounds natural, especially in a technical, descriptive, or educational context.

It has a slightly formal or analytical tone because of acúfeno, so it fits well in:

• a medical explanation
• a textbook
• a clinical discussion
• an article comparing symptoms or sounds

In very casual speech, a speaker might choose less technical wording.
