El pedal hace ruido.

In Spanish, hacer ruido is a very common fixed expression meaning to make noise.

So instead of saying something like the pedal is noisy, Spanish often says the pedal makes noise:

• El pedal hace ruido. = The pedal makes noise.

You could also say:

• El pedal es ruidoso. = The pedal is noisy.

But that describes the pedal as generally noisy, while hace ruido often sounds more natural when talking about a specific annoying sound it is making.

Because the subject is el pedal, which is third person singular (it).

The verb hacer is conjugated like this in the present tense:

• yo hago
• tú haces
• él / ella / usted hace
• nosotros/as hacemos
• vosotros/as hacéis
• ellos / ellas / ustedes hacen

Since el pedal = it, you use hace.

Spanish usually uses articles more often than English.

So el pedal means the pedal. In a normal standalone sentence, Spanish generally prefers the article here.

Compare:

• El pedal hace ruido. = The pedal is making noise.

Without the article, pedal would usually sound incomplete or unnatural in this context.

Also, pedal is a masculine singular noun, so the article is el.

Not exactly. Nouns ending in consonants can be masculine or feminine. You simply have to learn the gender with the noun.

In this case, it is:

• el pedal
• los pedales

So the sentence uses el because pedal is masculine.

In the expression hacer ruido, Spanish normally leaves ruido without an article when it means to make noise in a general sense.

• Hace ruido. = It makes noise.

If you add an article, the meaning changes slightly:

• hace un ruido = it makes a noise / it makes a certain noise
• hace mucho ruido = it makes a lot of noise
• hace el ruido = usually it makes the noise, which is much more specific and less common in this kind of sentence

So hace ruido is the standard general expression.

Yes. Grammatically, ruido functions as the direct object of hacer in this expression.

Structure:

• El pedal = subject
• hace = verb
• ruido = direct object

Literally, it is The pedal makes noise.

Even though learners often memorize hacer ruido as a chunk, it is still useful to know how the sentence is built.

Yes. That is also correct, but it changes the feel slightly.

• El pedal hace ruido. = the pedal makes noise / is noisy
• El pedal está haciendo ruido. = the pedal is making noise right now

The present simple (hace) is very common in Spanish for current situations, so El pedal hace ruido can already mean that it is making noise now. The progressive form (está haciendo) adds more emphasis to the ongoing action.

Sometimes, but not always in exactly the same way.

• El pedal hace ruido. = The pedal is making noise.
• El pedal suena. = The pedal sounds / makes a sound.

Suena can sound a bit broader or less idiomatic in this exact mechanical context. If a bike pedal is creaking or rattling, hace ruido is usually the most natural everyday choice.

You might also hear more specific verbs depending on the sound:

• chirría = squeaks
• cruje = creaks
• traquetea = rattles

In Spanish, h is silent.

So hace is pronounced roughly like:

• in Spain: AH-theh or AH-seh, depending on accent

In most of Spain, the c before e is pronounced like the th in think:

• hace → AH-theh

In many other Spanish-speaking regions, it is pronounced like s:

• hace → AH-seh

But the h is silent everywhere.

Yes, but El pedal hace ruido is the most neutral and standard order.

Spanish word order is flexible, so you might also hear:

• Hace ruido el pedal.

This can sound more marked or more conversational, depending on context, as if the speaker is focusing on the fact that it makes noise first.

Still, for learners, the basic order is best:

• subject + verb + object
• El pedal hace ruido.

You make both the noun and the verb plural:

• Los pedales hacen ruido. = The pedals make noise.

Changes:

• el → los
• pedal → pedales
• hace → hacen

So the verb must agree with the subject.

Not necessarily. El pedal could refer to a bicycle pedal, a car pedal, a sewing machine pedal, or another pedal, depending on context.

The sentence itself does not tell you which one. Spanish works the same way as English here: the surrounding context tells you what kind of pedal is meant.
