Yes, when Kenpachi was laughing, like you said in the other answer. But at other times, when Kenpachi was just standing idle, he would need some way to know where Kenpachi was otherwise he could not attack.

<p>When Tōsen attacks with Enma Kōrogi, He is not affected by it as anyone else (he can still smell and hear).<br>
So when he asked why Kenpachi laughs it was because he could <a href="https://i.sstatic.net/GviJk.jpg" rel="nofollow noreferrer">hear</a> him laughing.</p>

Are you sure he *heard* him laughing? I was pretty sure he smiled.

<p>When Tosen fights Kenpachi in the <em>Rescue Rukia</em> arc, Tosen uses his bankai to combat Kenpachi.</p>

<p>A while later, Kenpachi figures out how to defeat Tosen's bankai and smiles. Tosen somehow knew that he smiled (Because we heard his thoughts: "He's smiling?")</p>

<p>However, <strong>Tosen is blind</strong>. How could he have known?</p>

How could Tosen know that Kenpachi was smiling?

However, **Tosen is blind**. How could he have known?

When Tōsen attacks with Enma Kōrogi, He is not affected by it as anyone else (he can still smell and hear).  
So when he asked why Kenpachi laughs it was because he could [hear](https://i.sstatic.net/GviJk.jpg) him laughing.
