Answer 1

You are referring to verses 7-8 of Adhyaya 2 Brahmana 4 of the Brihadaranyaka Upanishad:

sa yathā dundubherhanyamānasya na bāhyāñchabdāñchaknuyādgrahaṇāya, dundubhestu grahaṇena—dundubhyāghātasya vā—śabdō gṛhītaḥ ||
sa yathā śaṅkhasya dhmāyamānasya na bāhyāñchabdāñchaknuyādgrahaṇāya, śaṅkhasya tu grahaṇena—śaṅkhadhmasya vā—śabdō gṛhītaḥ ||

The word translated as seizing is grahaṇa.
