What is the character `bia` in `bia响`? In this video 方清平《春节记事》单口相声笑侃春节趣闻轶事 there's a short part of a sentence at around ~4:46 where the speaker says:


  往地一摔 bia响了


The subtitles themselves leave out bia and just go for:


  往地一摔 响了


I went through 北京话词典 but it just goes from:


避屈 bìqū 


to


边边儿沿沿儿 biānbiānryán yánr 


In other dialects I've seen bia written: 扁、瘪 and .

I've seen 嘌 noted as "pia" it might be an option with the confusion of b/p.

Any ideas?
Here are two characters that have the pronunciation bia:


拼音bia4
㈠邑名。
㈡姓。



㈠bia4,上下相付。


zdic has a question that reads:

从小有个朋友问我“bia”拼出来的汉字怎么写，我当时真懵了，不会啊！时间过去20年了，突然回想起这个拼音，有会写的么，请告知，谢谢了

the last comment says:

8楼14楼是权威说法。

Number eight reads:

pia、bia、diang，其实就是pa、ba、dang的变读。
方法是在声母与韵母间插入“i ” 。
例子太多了，就不列举了。

and number fourteen says:

多以“吧”字代之。如吧叽，吧嗒。吧读bia.

《哈尔滨方言词典》p. 110



Simply lists all bia:

□

but the same words from the zdic thread are written as:

吧叽

and

吧嗒

Seemingly making 吧 an acceptable candidate.

《北京方言词典》陈刚 商务印书馆 1985 p.17 confirms this assumption:
