is a verb that is often used to describe things that can be heard, or the way in which something is heard. Because of this, the most common translations of this verb are ‘to be audible’, or ‘to sound like (A)’. 聞（き）こえる
is an intransitive verb, and literally means ‘to give off sound’.
When using 聞（き）こえる
, (A) will always be followed by が
. (A) is considered to be the ‘source’ of the sound (a noun). However, the ‘way that something sounds’ will be marked adverbially. This means that an い-Adjective
will be changed to its く form, and な-Adjectives
/nouns will be followed by に

It sounds like a train, but that is the neighbor’s snoring.
The primary difference between 聞（き）こえる
, and 聞（き）ける
form of 聞（き）く), is that 聞（き）こえる
is used to identify things that do not require the active concentration of the listener to be heard. In other words, ambient noise. However, 聞（き）ける
is used when the speaker is trying to concentrate on some specific sound, and refers to their ‘ability’ to hear it.

If you are in a quiet room, you can hear it. (If you focus and try to hear the sound)
